1The libffi source distribution contains certain code that is not part 2of libffi, and is only used as tooling to assist with the building and 3testing of libffi. This includes the msvcc.sh script used to wrap the 4Microsoft compiler with GNU compatible command-line options, 5make_sunver.pl, and the libffi test code distributed in the 6testsuite/libffi.bhaible directory. This code is distributed with 7libffi for the purpose of convenience only, and libffi is in no way 8derived from this code. 9 10msvcc.sh an testsuite/libffi.bhaible are both distributed under the 11terms of the GNU GPL version 2, as below. 12 13 14 15 GNU GENERAL PUBLIC LICENSE 16 Version 2, June 1991 17 18 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 19 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 20 Everyone is permitted to copy and distribute verbatim copies 21 of this license document, but changing it is not allowed. 22 23 Preamble 24 25 The licenses for most software are designed to take away your 26freedom to share and change it. By contrast, the GNU General Public 27License is intended to guarantee your freedom to share and change free 28software--to make sure the software is free for all its users. This 29General Public License applies to most of the Free Software 30Foundation's software and to any other program whose authors commit to 31using it. (Some other Free Software Foundation software is covered by 32the GNU Lesser General Public License instead.) You can apply it to 33your programs, too. 34 35 When we speak of free software, we are referring to freedom, not 36price. Our General Public Licenses are designed to make sure that you 37have the freedom to distribute copies of free software (and charge for 38this service if you wish), that you receive source code or can get it 39if you want it, that you can change the software or use pieces of it 40in new free programs; and that you know you can do these things. 41 42 To protect your rights, we need to make restrictions that forbid 43anyone to deny you these rights or to ask you to surrender the rights. 44These restrictions translate to certain responsibilities for you if you 45distribute copies of the software, or if you modify it. 46 47 For example, if you distribute copies of such a program, whether 48gratis or for a fee, you must give the recipients all the rights that 49you have. You must make sure that they, too, receive or can get the 50source code. And you must show them these terms so they know their 51rights. 52 53 We protect your rights with two steps: (1) copyright the software, and 54(2) offer you this license which gives you legal permission to copy, 55distribute and/or modify the software. 56 57 Also, for each author's protection and ours, we want to make certain 58that everyone understands that there is no warranty for this free 59software. If the software is modified by someone else and passed on, we 60want its recipients to know that what they have is not the original, so 61that any problems introduced by others will not reflect on the original 62authors' reputations. 63 64 Finally, any free program is threatened constantly by software 65patents. We wish to avoid the danger that redistributors of a free 66program will individually obtain patent licenses, in effect making the 67program proprietary. To prevent this, we have made it clear that any 68patent must be licensed for everyone's free use or not licensed at all. 69 70 The precise terms and conditions for copying, distribution and 71modification follow. 72 73 GNU GENERAL PUBLIC LICENSE 74 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 75 76 0. This License applies to any program or other work which contains 77a notice placed by the copyright holder saying it may be distributed 78under the terms of this General Public License. The "Program", below, 79refers to any such program or work, and a "work based on the Program" 80means either the Program or any derivative work under copyright law: 81that is to say, a work containing the Program or a portion of it, 82either verbatim or with modifications and/or translated into another 83language. (Hereinafter, translation is included without limitation in 84the term "modification".) Each licensee is addressed as "you". 85 86Activities other than copying, distribution and modification are not 87covered by this License; they are outside its scope. The act of 88running the Program is not restricted, and the output from the Program 89is covered only if its contents constitute a work based on the 90Program (independent of having been made by running the Program). 91Whether that is true depends on what the Program does. 92 93 1. You may copy and distribute verbatim copies of the Program's 94source code as you receive it, in any medium, provided that you 95conspicuously and appropriately publish on each copy an appropriate 96copyright notice and disclaimer of warranty; keep intact all the 97notices that refer to this License and to the absence of any warranty; 98and give any other recipients of the Program a copy of this License 99along with the Program. 100 101You may charge a fee for the physical act of transferring a copy, and 102you may at your option offer warranty protection in exchange for a fee. 103 104 2. You may modify your copy or copies of the Program or any portion 105of it, thus forming a work based on the Program, and copy and 106distribute such modifications or work under the terms of Section 1 107above, provided that you also meet all of these conditions: 108 109 a) You must cause the modified files to carry prominent notices 110 stating that you changed the files and the date of any change. 111 112 b) You must cause any work that you distribute or publish, that in 113 whole or in part contains or is derived from the Program or any 114 part thereof, to be licensed as a whole at no charge to all third 115 parties under the terms of this License. 116 117 c) If the modified program normally reads commands interactively 118 when run, you must cause it, when started running for such 119 interactive use in the most ordinary way, to print or display an 120 announcement including an appropriate copyright notice and a 121 notice that there is no warranty (or else, saying that you provide 122 a warranty) and that users may redistribute the program under 123 these conditions, and telling the user how to view a copy of this 124 License. (Exception: if the Program itself is interactive but 125 does not normally print such an announcement, your work based on 126 the Program is not required to print an announcement.) 127 128These requirements apply to the modified work as a whole. If 129identifiable sections of that work are not derived from the Program, 130and can be reasonably considered independent and separate works in 131themselves, then this License, and its terms, do not apply to those 132sections when you distribute them as separate works. But when you 133distribute the same sections as part of a whole which is a work based 134on the Program, the distribution of the whole must be on the terms of 135this License, whose permissions for other licensees extend to the 136entire whole, and thus to each and every part regardless of who wrote it. 137 138Thus, it is not the intent of this section to claim rights or contest 139your rights to work written entirely by you; rather, the intent is to 140exercise the right to control the distribution of derivative or 141collective works based on the Program. 142 143In addition, mere aggregation of another work not based on the Program 144with the Program (or with a work based on the Program) on a volume of 145a storage or distribution medium does not bring the other work under 146the scope of this License. 147 148 3. You may copy and distribute the Program (or a work based on it, 149under Section 2) in object code or executable form under the terms of 150Sections 1 and 2 above provided that you also do one of the following: 151 152 a) Accompany it with the complete corresponding machine-readable 153 source code, which must be distributed under the terms of Sections 154 1 and 2 above on a medium customarily used for software interchange; or, 155 156 b) Accompany it with a written offer, valid for at least three 157 years, to give any third party, for a charge no more than your 158 cost of physically performing source distribution, a complete 159 machine-readable copy of the corresponding source code, to be 160 distributed under the terms of Sections 1 and 2 above on a medium 161 customarily used for software interchange; or, 162 163 c) Accompany it with the information you received as to the offer 164 to distribute corresponding source code. (This alternative is 165 allowed only for noncommercial distribution and only if you 166 received the program in object code or executable form with such 167 an offer, in accord with Subsection b above.) 168 169The source code for a work means the preferred form of the work for 170making modifications to it. For an executable work, complete source 171code means all the source code for all modules it contains, plus any 172associated interface definition files, plus the scripts used to 173control compilation and installation of the executable. However, as a 174special exception, the source code distributed need not include 175anything that is normally distributed (in either source or binary 176form) with the major components (compiler, kernel, and so on) of the 177operating system on which the executable runs, unless that component 178itself accompanies the executable. 179 180If distribution of executable or object code is made by offering 181access to copy from a designated place, then offering equivalent 182access to copy the source code from the same place counts as 183distribution of the source code, even though third parties are not 184compelled to copy the source along with the object code. 185 186 4. You may not copy, modify, sublicense, or distribute the Program 187except as expressly provided under this License. Any attempt 188otherwise to copy, modify, sublicense or distribute the Program is 189void, and will automatically terminate your rights under this License. 190However, parties who have received copies, or rights, from you under 191this License will not have their licenses terminated so long as such 192parties remain in full compliance. 193 194 5. You are not required to accept this License, since you have not 195signed it. However, nothing else grants you permission to modify or 196distribute the Program or its derivative works. These actions are 197prohibited by law if you do not accept this License. Therefore, by 198modifying or distributing the Program (or any work based on the 199Program), you indicate your acceptance of this License to do so, and 200all its terms and conditions for copying, distributing or modifying 201the Program or works based on it. 202 203 6. Each time you redistribute the Program (or any work based on the 204Program), the recipient automatically receives a license from the 205original licensor to copy, distribute or modify the Program subject to 206these terms and conditions. You may not impose any further 207restrictions on the recipients' exercise of the rights granted herein. 208You are not responsible for enforcing compliance by third parties to 209this License. 210 211 7. If, as a consequence of a court judgment or allegation of patent 212infringement or for any other reason (not limited to patent issues), 213conditions are imposed on you (whether by court order, agreement or 214otherwise) that contradict the conditions of this License, they do not 215excuse you from the conditions of this License. If you cannot 216distribute so as to satisfy simultaneously your obligations under this 217License and any other pertinent obligations, then as a consequence you 218may not distribute the Program at all. For example, if a patent 219license would not permit royalty-free redistribution of the Program by 220all those who receive copies directly or indirectly through you, then 221the only way you could satisfy both it and this License would be to 222refrain entirely from distribution of the Program. 223 224If any portion of this section is held invalid or unenforceable under 225any particular circumstance, the balance of the section is intended to 226apply and the section as a whole is intended to apply in other 227circumstances. 228 229It is not the purpose of this section to induce you to infringe any 230patents or other property right claims or to contest validity of any 231such claims; this section has the sole purpose of protecting the 232integrity of the free software distribution system, which is 233implemented by public license practices. Many people have made 234generous contributions to the wide range of software distributed 235through that system in reliance on consistent application of that 236system; it is up to the author/donor to decide if he or she is willing 237to distribute software through any other system and a licensee cannot 238impose that choice. 239 240This section is intended to make thoroughly clear what is believed to 241be a consequence of the rest of this License. 242 243 8. If the distribution and/or use of the Program is restricted in 244certain countries either by patents or by copyrighted interfaces, the 245original copyright holder who places the Program under this License 246may add an explicit geographical distribution limitation excluding 247those countries, so that distribution is permitted only in or among 248countries not thus excluded. In such case, this License incorporates 249the limitation as if written in the body of this License. 250 251 9. The Free Software Foundation may publish revised and/or new versions 252of the General Public License from time to time. Such new versions will 253be similar in spirit to the present version, but may differ in detail to 254address new problems or concerns. 255 256Each version is given a distinguishing version number. If the Program 257specifies a version number of this License which applies to it and "any 258later version", you have the option of following the terms and conditions 259either of that version or of any later version published by the Free 260Software Foundation. If the Program does not specify a version number of 261this License, you may choose any version ever published by the Free Software 262Foundation. 263 264 10. If you wish to incorporate parts of the Program into other free 265programs whose distribution conditions are different, write to the author 266to ask for permission. For software which is copyrighted by the Free 267Software Foundation, write to the Free Software Foundation; we sometimes 268make exceptions for this. Our decision will be guided by the two goals 269of preserving the free status of all derivatives of our free software and 270of promoting the sharing and reuse of software generally. 271 272 NO WARRANTY 273 274 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 275FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 276OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 277PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 278OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 279MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 280TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 281PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 282REPAIR OR CORRECTION. 283 284 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 285WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 286REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 287INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 288OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 289TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 290YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 291PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 292POSSIBILITY OF SUCH DAMAGES. 293 294 END OF TERMS AND CONDITIONS 295 296 How to Apply These Terms to Your New Programs 297 298 If you develop a new program, and you want it to be of the greatest 299possible use to the public, the best way to achieve this is to make it 300free software which everyone can redistribute and change under these terms. 301 302 To do so, attach the following notices to the program. It is safest 303to attach them to the start of each source file to most effectively 304convey the exclusion of warranty; and each file should have at least 305the "copyright" line and a pointer to where the full notice is found. 306 307 <one line to give the program's name and a brief idea of what it does.> 308 Copyright (C) <year> <name of author> 309 310 This program is free software; you can redistribute it and/or modify 311 it under the terms of the GNU General Public License as published by 312 the Free Software Foundation; either version 2 of the License, or 313 (at your option) any later version. 314 315 This program is distributed in the hope that it will be useful, 316 but WITHOUT ANY WARRANTY; without even the implied warranty of 317 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 318 GNU General Public License for more details. 319 320 You should have received a copy of the GNU General Public License along 321 with this program; if not, write to the Free Software Foundation, Inc., 322 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. 323 324Also add information on how to contact you by electronic and paper mail. 325 326If the program is interactive, make it output a short notice like this 327when it starts in an interactive mode: 328 329 Gnomovision version 69, Copyright (C) year name of author 330 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 331 This is free software, and you are welcome to redistribute it 332 under certain conditions; type `show c' for details. 333 334The hypothetical commands `show w' and `show c' should show the appropriate 335parts of the General Public License. Of course, the commands you use may 336be called something other than `show w' and `show c'; they could even be 337mouse-clicks or menu items--whatever suits your program. 338 339You should also get your employer (if you work as a programmer) or your 340school, if any, to sign a "copyright disclaimer" for the program, if 341necessary. Here is a sample; alter the names: 342 343 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 344 `Gnomovision' (which makes passes at compilers) written by James Hacker. 345 346 <signature of Ty Coon>, 1 April 1989 347 Ty Coon, President of Vice 348 349This General Public License does not permit incorporating your program into 350proprietary programs. If your program is a subroutine library, you may 351consider it more useful to permit linking proprietary applications with the 352library. If this is what you want to do, use the GNU Lesser General 353Public License instead of this License. 354
