The preprocessor does not define builtin macros for its command line 
options.

You could, perhaps, use a shell construct to check for the presence
of -Werror on the command line, then set the compiler options 
accordingly.

I had been planning such a feature in ctpp (shamless OT plug, I know), 
but there hasn't been any demand so far.
