1.12 +## Name: glibcversion.sh - Print __GLIBC__ version if gnu libc 2 is
1.13 +## found.
1.14 +##
1.15 +## Description: This script is needed by the mozilla build system. It needs
1.16 +## to determine whether the current platform (mostly the
1.17 +## various linux "platforms") are based on the gnu libc2. This
1.18 +## information is later used in mozilla to determine whether
1.19 +## gnu libc 2 specific "features" need to be handled, such
1.20 +## as broken locales.
