| 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. | |
