Neither. Neither are portable, so the do not belong in the,
check for gcc in configure and append them to CFLAGS if they work.

I didn't know they weren't portable.  Our project requires gcc as a
precondition, but I see your point.  Is there a configure test to see
if -Wall works?

These options only work with GCC. If the compiler is GCC you can use them, otherwise skip them.

The Intel compiler recognizes -Wall and -Werror (but not -pedantic in
the version I have at hand).
