Weird. But it probably makes sense somehow. I think the original issue is that one should not **explicitly** say "omit frame pointers" and "instrument for profiling with mcount". It's possible that there should be other errors for using "omit frame pointers" on targets that require them, but that should be checked independently elsewhere. Do we have many (any) of these kinds of targets? I'm going to submit this patch, but am happy to add a diagnostic later on for the other case, if you think that is worthwhile.
