     9 ## Name:		glibcversion.sh - Print __GLIBC__ version if gnu libc 2 is

    10 ##              found.

    11 ##

    12 ## Description:	This script is needed by the mozilla build system.  It needs

    13 ##              to determine whether the current platform (mostly the

    14 ##              various linux "platforms") are based on the gnu libc2.  This

    15 ##              information is later used in mozilla to determine whether

    16 ##              gnu libc 2 specific "features" need to be handled, such

    17 ##              as broken locales.
