[Bug driver/15303] New: When gcc sees an unrecognized option, the exit status indicates success

["ian at wasabisystems dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When gcc is invoked with an unrecognized option, it reports an error, but still
exits with a zero exit status indicating success.  This is not how most Unix
programs work.  I can't think of any reason why gcc should work that way.

For example:

gossamer> gcc -R/tmp -o hello hello.o
gcc: unrecognized option `-R/tmp'
gossamer> echo $?
0

Compare with:

gossamer> cat -q
cat: invalid option -- q
Try `cat --help' for more information.
gossamer> echo $?
1

Note that gcc has acted this way at least since 2.95.3.  Still, it seems wrong
to me.
