The 90included version has been heavily modified by Rich Felker in 2012, in 91the interests of size, simplicity, and namespace cleanliness. 92 93Much of the math library code (src/math/* and src/complex/*) is 94Copyright © 1993,2004 Sun Microsystems or 95Copyright © 2003-2011 David Schultz or 96Copyright © 2003-2009 Steven G.

It was taken from Bionic libc, used on Android. 105 106The implementation of DES for crypt (src/misc/crypt_des.c) is 107Copyright © 1994 David Burren. It is licensed under a BSD license. 108 109The implementation of blowfish crypt (src/misc/crypt_blowfish.c) was 110originally written by Solar Designer and placed into the public 111domain. The code also comes with a fallback permissive license for use 112in jurisdictions that may not recognize the public domain. 113 114The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011 115Valentin Ochs and is licensed under an MIT-style license. 116 117The BSD PRNG implementation (src/prng/random.c) and XSI search API 118(src/search/*.c) functions are Copyright © 2011 Szabolcs Nagy and 119licensed under following terms: "Permission to use, copy, modify, 120and/or distribute this code for any purpose with or without fee is 121hereby granted.

Several files (crt) 124were released into the public domain; others are licensed under the 125standard MIT license terms at the top of this file. See individual 126files for their copyright status. 127 128The mips and microblaze ports were originally written by Richard 129Pennington for use in the ellcc project. The original code was adapted 130by Rich Felker for build system and code conventions during upstream 131integration. It is licensed under the standard MIT terms. 132 133The powerpc port was also originally written by Richard Pennington, 134and later supplemented and integrated by John Spencer. It is licensed 135under the standard MIT terms. 136 137All other files which have no copyright comments are original works 138produced specifically for use as part of this library, written either 139by Rich Felker, the main author of the library, or by one or more 140contibutors listed above. Details on authorship of individual files 141can be found in the git version control history of the project. The 142omission of copyright and license comments in each file is in the 143interest of source tree size. 144 145All public header files (include/* and arch/*/bits/*) should be 146treated as Public Domain as they intentionally contain no content 147which can be covered by copyright. Some source modules may fall in 148this category as well. If you believe that a file is so trivial that 149it should be in the Public Domain, please contact the authors and 150request an explicit statement releasing it from copyright. 151 152The following files are trivial, believed not to be copyrightable in 153the first place, and hereby explicitly released to the Public Domain: 154 155All public headers: include/*, arch/*/bits/* 156Startup files: crt/* 157
