cproto use gcc via 'gcc -E' and is actually limit itself at grabbing func

Yes - but that smells like a complex task to overcome a change of
'functionality' that was there for decades in nearly every compiler :-)

Refuse to compile: Yes - I agree
Refuse to preproc: Seems a little bit harsh... and breaks stuffs actually
