21 separate executable file which are aggregated on a storage medium together
22 with another program, this in itself does not bring the other program under
23 the GPL, nor does the mere fact that such a program or the procedures for
24 constructing it invoke the ansi2knr executable bring any other part of the
25 program under the GPL.

32 GHOSTSCRIPT GENERAL PUBLIC LICENSE
33 (Clarified 11 Feb 1988)
34
35 Copyright (C) 1988 Richard M. Stallman
36 Everyone is permitted to copy and distribute verbatim copies of this
37 license, but changing it is not allowed. You can also use this wording
38 to make the terms for other programs.
39
40 The license agreements of most software companies keep you at the
41 mercy of those companies. By contrast, our general public license is
42 intended to give everyone the right to share Ghostscript. To make sure
43 that you get the rights we want you to have, we need to make
44 restrictions that forbid anyone to deny you these rights or to ask you
45 to surrender the rights. Hence this license agreement.
46
47 Specifically, we want to make sure that you have the right to give
48 away copies of Ghostscript, that you receive source code or else can get
49 it if you want it, that you can change Ghostscript or use pieces of it
50 in new free programs, and that you know you can do these things.
51
52 To make sure that everyone has such rights, we have to forbid you to
53 deprive anyone else of these rights. For example, if you distribute
54 copies of Ghostscript, you must give the recipients all the rights that
55 you have. You must make sure that they, too, receive or can get the
56 source code. And you must tell them their rights.
57
58 Also, for our own protection, we must make certain that everyone finds
59 out that there is no warranty for Ghostscript. If Ghostscript is
60 modified by someone else and passed on, we want its recipients to know
61 that what they have is not what we distributed, so that any problems
62 introduced by others will not reflect on our reputation.
63
64 Therefore we (Richard M. Stallman and the Free Software Foundation,
65 Inc.) make the following terms which say what you must do to be allowed
66 to distribute or change Ghostscript.
67
68
69 COPYING POLICIES
70
71 1. You may copy and distribute verbatim copies of Ghostscript source
72 code as you receive it, in any medium, provided that you conspicuously
73 and appropriately publish on each copy a valid copyright and license
74 notice "Copyright (C) 1989 Aladdin Enterprises. All rights reserved.
75 Distributed by Free Software Foundation, Inc." (or with whatever year is
76 appropriate); keep intact the notices on all files that refer to this
77 License Agreement and to the absence of any warranty; and give any other
78 recipients of the Ghostscript program a copy of this License Agreement
79 along with the program. You may charge a distribution fee for the
80 physical act of transferring a copy.
81
82 2. You may modify your copy or copies of Ghostscript or any portion of
83 it, and copy and distribute such modifications under the terms of
84 Paragraph 1 above, provided that you also do the following:
85
86 a) cause the modified files to carry prominent notices stating
87 that you changed the files and the date of any change; and
88
89 b) cause the whole of any work that you distribute or publish,
90 that in whole or in part contains or is a derivative of Ghostscript
91 or any part thereof, to be licensed at no charge to all third
92 parties on terms identical to those contained in this License
93 Agreement (except that you may choose to grant more extensive
94 warranty protection to some or all third parties, at your option).
95
96 c) You may charge a distribution fee for the physical act of
97 transferring a copy, and you may at your option offer warranty
98 protection in exchange for a fee.
99
100 Mere aggregation of another unrelated program with this program (or its
101 derivative) on a volume of a storage or distribution medium does not bring
102 the other program under the scope of these terms.
103
104 3. You may copy and distribute Ghostscript (or a portion or derivative
105 of it, under Paragraph 2) in object code or executable form under the
106 terms of Paragraphs 1 and 2 above provided that you also do one of the
107 following:
108
109 a) accompany it with the complete corresponding machine-readable
110 source code, which must be distributed under the terms of
111 Paragraphs 1 and 2 above; or,
112
113 b) accompany it with a written offer, valid for at least three
114 years, to give any third party free (except for a nominal
115 shipping charge) a complete machine-readable copy of the
116 corresponding source code, to be distributed under the terms of
117 Paragraphs 1 and 2 above; or,
118
119 c) accompany it with the information you received as to where the
120 corresponding source code may be obtained. (This alternative is
121 allowed only for noncommercial distribution and only if you
122 received the program in object code or executable form alone.)
123
124 For an executable file, complete source code means all the source code for
125 all modules it contains; but, as a special exception, it need not include
126 source code for modules which are standard libraries that accompany the
127 operating system on which the executable file runs.
128
129 4. You may not copy, sublicense, distribute or transfer Ghostscript
130 except as expressly provided under this License Agreement. Any attempt
131 otherwise to copy, sublicense, distribute or transfer Ghostscript is
132 void and your rights to use the program under this License agreement
133 shall be automatically terminated. However, parties who have received
134 computer software programs from you with this License Agreement will not
135 have their licenses terminated so long as such parties remain in full
136 compliance.
137
138 5. If you wish to incorporate parts of Ghostscript into other free
139 programs whose distribution conditions are different, write to the Free
140 Software Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not
141 yet worked out a simple rule that can be stated here, but we will often
142 permit this. We will be guided by the two goals of preserving the free
143 status of all derivatives of our free software and of promoting the
144 sharing and reuse of software.
145
146 Your comments and suggestions about our licensing policies and our
147 software are welcome! Please contact the Free Software Foundation,
148 Inc., 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.
149
150 NO WARRANTY
151
152 BECAUSE GHOSTSCRIPT IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY
153 NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT
154 WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, RICHARD
155 M. STALLMAN, ALADDIN ENTERPRISES, L. PETER DEUTSCH, AND/OR OTHER PARTIES
156 PROVIDE GHOSTSCRIPT "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
157 EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
158 WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
159 ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF GHOSTSCRIPT IS WITH
160 YOU. SHOULD GHOSTSCRIPT PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
161 NECESSARY SERVICING, REPAIR OR CORRECTION.
162
163 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
164 STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., L. PETER DEUTSCH, ALADDIN
165 ENTERPRISES, AND/OR ANY OTHER PARTY WHO MAY MODIFY AND REDISTRIBUTE
166 GHOSTSCRIPT AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
167 ANY LOST PROFITS, LOST MONIES, OR OTHER SPECIAL, INCIDENTAL OR
168 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
169 (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
170 INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A FAILURE OF THE
171 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GHOSTSCRIPT, EVEN IF YOU
172 HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM
173 BY ANY OTHER PARTY.

179 * Usage:
180 ansi2knr input_file [output_file]
181 * If no output_file is supplied, output goes to stdout.
182 * There are no error messages.
183 *
184 * ansi2knr recognizes function definitions by seeing a non-keyword
185 * identifier at the left margin, followed by a left parenthesis,
186 * with a right parenthesis as the last character on the line,
187 * and with a left brace as the first token on the following line
188 * (ignoring possible intervening comments).
189 * It will recognize a multi-line header provided that no intervening
190 * line ends with a left or right brace or a semicolon.
191 * These algorithms ignore whitespace and comments, except that
192 * the function name must be the first thing on the line.
193 * The following constructs will confuse it:
194 * - Any other construct that starts at the left margin and
195 * follows the above syntax (such as a macro or function call).
196 * - Some macros that tinker with the syntax of the function header.

201 * <ghost@aladdin.com>. Other authors are noted in the change history
202 * that follows (in reverse chronological order):
203 lpd 96-01-21 added code to cope with not HAVE_CONFIG_H and with
204 compilers that don't understand void, as suggested by
205 Tom Lane
206 lpd 96-01-15 changed to require that the first non-comment token
207 on the line following a function header be a left brace,
208 to reduce sensitivity to macros, as suggested by Tom Lane
209 <tgl@sss.pgh.pa.us>
210 lpd 95-06-22 removed #ifndefs whose sole purpose was to define
211 undefined preprocessor symbols as 0; changed all #ifdefs
212 for configuration symbols to #ifs
213 lpd 95-04-05 changed copyright notice to make it clear that
214 including ansi2knr in a program does not bring the entire
215 program under the GPL
216 lpd 94-12-18 added conditionals for systems where ctype macros
217 don't handle 8-bit characters properly, suggested by
218 Francois Pinard <pinard@iro.umontreal.ca>;
219 removed --varargs switch (this is now the default)
220 lpd 94-10-10 removed CONFIG_BROKETS conditional
221 lpd 94-07-16 added some conditionals to help GNU `configure',
222 suggested by Francois Pinard <pinard@iro.umontreal.ca>;
223 properly erase prototype args in function parameters,
224 contributed by Jim Avera <jima@netcom.com>;
225 correct error in writeblanks (it shouldn't erase EOLs)
