The 85included version has been heavily modified by Rich Felker in 2012, in 86the interests of size, simplicity, and namespace cleanliness. 87 88Much of the math library code (src/math/* and src/complex/*) is 89Copyright © 1993,2004 Sun Microsystems or 90Copyright © 2003-2011 David Schultz or 91Copyright © 2003-2009 Steven G.

It was taken from Bionic libc, used on Android. 100 101The implementation of DES for crypt (src/crypt/crypt_des.c) is 102Copyright © 1994 David Burren. It is licensed under a BSD license. 103 104The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was 105originally written by Solar Designer and placed into the public 106domain. The code also comes with a fallback permissive license for use 107in jurisdictions that may not recognize the public domain. 108 109The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011 110Valentin Ochs and is licensed under an MIT-style license. 111 112The BSD PRNG implementation (src/prng/random.c) and XSI search API 113(src/search/*.c) functions are Copyright © 2011 Szabolcs Nagy and 114licensed under following terms: "Permission to use, copy, modify, 115and/or distribute this code for any purpose with or without fee is 116hereby granted.

Kain and is licensed under 119the standard MIT terms. 120 121The mips and microblaze ports were originally written by Richard 122Pennington for use in the ellcc project. The original code was adapted 123by Rich Felker for build system and code conventions during upstream 124integration. It is licensed under the standard MIT terms. 125 126The mips64 port was contributed by Imagination Technologies and is 127licensed under the standard MIT terms. 128 129The powerpc port was also originally written by Richard Pennington, 130and later supplemented and integrated by John Spencer. It is licensed 131under the standard MIT terms. 132 133All other files which have no copyright comments are original works 134produced specifically for use as part of this library, written either 135by Rich Felker, the main author of the library, or by one or more 136contibutors listed above. Details on authorship of individual files 137can be found in the git version control history of the project.

In the spirit of 162permissive licensing, and of not having licensing issues being an 163obstacle to adoption, that text has been removed. 164
