## 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.
