 The GNU C Library is the standard system C library for all GNU systems,
 and is an important part of what makes up a GNU system.  It provides the
 system API for all programs written in C and C-compatible languages such
 as C++ and Objective C; the runtime facilities of other programming
 languages use the C library to access the underlying operating system.

 This package installs the 32 bit libraries for x86_64 systems."
