Subject[PATCH][RESEND] improve scripts/gcc-version.sh output a bit when called without args
Date
(Resend of patch from 7 May 2007 17:18:00)


Currently, if you call scripts/gcc-version.sh without arguments it will
generate this output :

$ sh scripts/gcc-version.sh
scripts/gcc-version.sh: line 12: [: =: unary operator expected
scripts/gcc-version.sh: line 16: -E: command not found
scripts/gcc-version.sh: line 17: -E: command not found
0000

Not too pretty. I believe this is an improvement :

$ sh scripts/gcc-version.sh
Error: No compiler specified.
Usage:
scripts/gcc-version.sh <gcc-command>
