## 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.
