--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-02-07 18:05:36 UTC --- The testcase is bad, because for vanilla gcc releases there is no (prerelease) etc. string at all (DEV-PHASE is empty), and because it hardcodes ASCII values, so I'm afraid it could fail on EBCDIC or other targets.
