under terms compatible with the above MIT license:

114
The TRE regular expression implementation (src/regex/reg* and
115
src/regex/tre*) is Copyright © 2001-2008 Ville Laurikari and licensed
116
under a 2-clause BSD license (license text in the source files). The
117
included version has been heavily modified by Rich Felker in 2012, in
118
the interests of size, simplicity, and namespace cleanliness.
119

120
Much of the math library code (src/math/* and src/complex/*) is
121
Copyright © 1993,2004 Sun Microsystems or

127
and labelled as such in comments in the individual source files. All
128
have been licensed under extremely permissive terms.
129

130
The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
131
The Android Open Source Project and is licensed under a two-clause BSD
132
license. It was taken from Bionic libc, used on Android.
133

134
The AArch64 memcpy and memset code (src/string/aarch64/*) are
135
Copyright © 1999-2019, Arm Limited.
136

137
The implementation of DES for crypt (src/crypt/crypt_des.c) is
138
Copyright © 1994 David Burren. It is licensed under a BSD license.
139

140
The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
141
originally written by Solar Designer and placed into the public
142
domain. The code also comes with a fallback permissive license for use
143
in jurisdictions that may not recognize the public domain.
144

145
The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
146
Valentin Ochs and is licensed under an MIT-style license.
147

148
The x86_64 port was written by Nicholas J. Kain and is licensed under
149
the standard MIT terms.
150

151
The mips and microblaze ports were originally written by Richard
152
Pennington for use in the ellcc project. The original code was adapted
153
by Rich Felker for build system and code conventions during upstream
154
integration. It is licensed under the standard MIT terms.
155

156
The mips64 port was contributed by Imagination Technologies and is
157
licensed under the standard MIT terms.
158

159
The powerpc port was also originally written by Richard Pennington,
160
and later supplemented and integrated by John Spencer. It is licensed
161
under the standard MIT terms.
162

163
All other files which have no copyright comments are original works
164
produced specifically for use as part of this library, written either
165
by Rich Felker, the main author of the library, or by one or more
166
contibutors listed above. Details on authorship of individual files
167
can be found in the git version control history of the project. The
168
omission of copyright and license comments in each file is in the
169
interest of source tree size.
170

171
In addition, permission is hereby granted for all public header files
172
(include/* and arch/*/bits/*) and crt files intended to be linked into
173
applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit
174
the copyright notice and permission notice otherwise required by the
175
license, and to use these files without any requirement of
176
attribution. These files include substantial contributions from:
177

178
Bobby Bingham
179
John Spencer
180
Nicholas J. Kain
181
Rich Felker
182
Richard Pennington
183
Stefan Kristiansson
184
Szabolcs Nagy
185

186
all of whom have explicitly granted such permission.
187

188
This file previously contained text expressing a belief that most of
189
the files covered by the above exception were sufficiently trivial not
190
to be subject to copyright, resulting in confusion over whether it
191
negated the permissions granted in the license. In the spirit of
192
permissive licensing, and of not having licensing issues being an
193
obstacle to adoption, that text has been removed.
