## Name: glibcversion.sh - Print __GLIBC__ version if gnu libc 2 is
## found.
##
## Description: This script is needed by the mozilla build system. It needs
## to determine whether the current platform (mostly the
## various linux "platforms") are based on the gnu libc2. This
## information is later used in mozilla to determine whether
## gnu libc 2 specific "features" need to be handled, such
## as broken locales.
##
## Author: Ramiro Estrugo <ramiro@netscape.com>
