Glibc-2.40

The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more.

Libgw32c-0.4

This is an implementation of a small part of GLibC, just enough to compile most Unix programs on MS Windows. It contains functions for passwords, process id's groups, and strings. Most are interfaces to the MS-Windows Win32 API. Some are just dummy functions that do nothing..

Gsl-2.8

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite. Unlike the licenses of proprietary numerical libraries the license of GSL does not restrict scientific cooperation. It allows you to share your programs freely with others.
