It's not so much ghc, as _gcc_, because the extra whitespace/#pragmas
are inserted by the C preprocessor.  I believe the regexp currently in
CVS is correct (not "^#" and not "^$"), but perhaps an alternative which
actually searches for numbers on a line of their own (e.g. "^[0-9]*$")
might be better.
