These seem to be generated when gcc doesn't actually use a flag that has been passed to it. At Athena, I've got gcc configured to pass through a "-Z" flag to the linker; however, when "gcc -c" is used, it complains "unrecognized option `-Z'", but doesn't exit with an error status indication, and does perform the compilation. It should not flag as unrecognized options that it would recognize were it to invoke other programs, since it can indeed recognize those options. For options that are truly unrecognized, a non-zero exit status would be justified.
