Use -Wp to pass arbitrary parameters down to cpp.



Is this autodetected somewhere or is it always appropriate (cross-platform)? I'm just calling $ac_cpp in a macro. How do I know whether to pass -dM or -Wp,dM to $ac_cpp?

I often speculate on why you don't return to America.  Did you abscond with the
church funds?  Did you run off with the senator's wife?  I like to think that
you killed a man.  It's the romantic in me.
