Contributors to the GNU C Library
*********************************
The GNU C library was written originally by Roland McGrath, and is
currently maintained by Ulrich Drepper. Some parts of the library were
contributed or worked on by other people.
* The `getopt' function and related code was written by Richard
Stallman, David J. MacKenzie, and Roland McGrath.
* The merge sort function `qsort' was written by Michael J. Haertel.
* The quick sort function used as a fallback by `qsort' was written
by Douglas C. Schmidt.
* The memory allocation functions `malloc', `realloc' and `free' and
related code were written by Michael J. Haertel, Wolfram Gloger,
and Doug Lea.
* Fast implementations of many of the string functions (`memcpy',
`strlen', etc.) were written by Torbjo"rn Granlund.
* The `tar.h' header file was written by David J. MacKenzie.
* The port to the MIPS DECStation running Ultrix 4
(`mips-dec-ultrix4') was contributed by Brendan Kehoe and Ian
Lance Taylor.
* The DES encryption function `crypt' and related functions were
contributed by Michael Glad.
* The `ftw' and `nftw' functions were contributed by Ulrich Drepper.
* The startup code to support SunOS shared libraries was contributed
by Tom Quinn.
* The `mktime' function was contributed by Paul Eggert.
* The port to the Sequent Symmetry running Dynix version 3
(`i386-sequent-bsd') was contributed by Jason Merrill.
* The timezone support code is derived from the public-domain
timezone package by Arthur David Olson and his many contributors.
* The port to the DEC Alpha running OSF/1 (`alpha-dec-osf1') was
contributed by Brendan Kehoe, using some code written by Roland
McGrath.
* The port to SGI machines running Irix 4 (`mips-sgi-irix4') was
contributed by Tom Quinn.
* The port of the Mach and Hurd code to the MIPS architecture
(`mips-ANYTHING-gnu') was contributed by Kazumoto Kojima.
* The floating-point printing function used by `printf' and friends
and the floating-point reading function used by `scanf', `strtod'
and friends were written by Ulrich Drepper. The multi-precision
integer functions used in those functions are taken from GNU MP,
which was contributed by Torbjo"rn Granlund.
* The internationalization support in the library, and the support
programs `locale' and `localedef', were written by Ulrich Drepper.
Ulrich Drepper adapted the support code for message catalogs
(`libintl.h', etc.) from the GNU `gettext' package, which he also
wrote. He also contributed the `catgets' support and the entire
suite of multi-byte and wide-character support functions
(`wctype.h', `wchar.h', etc.).
* The implementations of the `nsswitch.conf' mechanism and the files
and DNS backends for it were designed and written by Ulrich
Drepper and Roland McGrath, based on a backend interface defined
by Peter Eriksson.
* The port to Linux i386/ELF (`i386-ANYTHING-linux') was contributed
by Ulrich Drepper, based in large part on work done in Hongjiu
Lu's Linux version of the GNU C Library.
* The port to Linux/m68k (`m68k-ANYTHING-linux') was contributed by
Andreas Schwab.
* The ports to Linux/ARM (`arm-ANYTHING-linuxaout') and ARM
standalone (`arm-ANYTHING-none'), as well as parts of the IPv6
support code, were contributed by Philip Blundell.
* Richard Henderson contributed the ELF dynamic linking code and
other support for the Alpha processor.
* David Mosberger-Tang contributed the port to Linux/Alpha
(`alpha-ANYTHING-linux').
* The port to Linux on PowerPC (`powerpc-ANYTHING-linux') was
contributed by Geoffrey Keating.
* Miles Bader wrote the argp argument-parsing package, and the
argz/envz interfaces.
* Stephen R. van den Berg contributed a highly-optimized `strstr'
function.
* Ulrich Drepper contributed the `hsearch' and `drand48' families of
functions; reentrant `...`_r'' versions of the `random' family;
System V shared memory and IPC support code; and several
highly-optimized string functions for iX86 processors.
* The math functions are taken from `fdlibm-5.1' by Sun
Microsystems, as modified by J.T. Conklin, Ian Lance Taylor,
Ulrich Drepper, Andreas Schwab, and Roland McGrath.
* The `libio' library used to implement `stdio' functions on some
platforms was written by Per Bothner and modified by Ulrich
Drepper.
* Eric Youngdale and Ulrich Drepper implemented versioning of
objects on symbol level.
* Thorsten Kukuk provided an implementation for NIS (YP) and NIS+,
securelevel 0, 1 and 2.
* Andreas Jaeger provided a test suite for the math library.
* Mark Kettenis implemented the utmpx interface and an utmp daemon.
* Ulrich Drepper added character conversion functions (`iconv').
* Thorsten Kukuk provided an implementation for a caching daemon for
NSS (nscd).
* Tim Waugh provided an implementation of the POSIX.2 wordexp
function family.
* Mark Kettenis provided a Hesiod NSS module.
* The Internet-related code (most of the `inet' subdirectory) and
several other miscellaneous functions and header files have been
included from 4.4 BSD with little or no modification.

* The random number generation functions `random', `srandom',
`setstate' and `initstate', which are also the basis for the
`rand' and `srand' functions, were written by Earl T. Cohen for
the University of California at Berkeley and are copyrighted by the
Regents of the University of California. They have undergone minor
changes to fit into the GNU C library and to fit the ISO C
standard, but the functional code is Berkeley's.
