Thanks.

I have to admit, I'm somewhat confused as to why iargc (and
command_argument_count) broke and getarg (and the f2003 stuff) worked,
although both were implemented very similarly, with NULL pointers to
all those check and resolve functions (in the original patches by Bud
and me). Or alternatively, why didn't getarg et. al. need their own
GFC_ISYM_XXX??

Yes, I was aware of that. Thought I'd try to fix it by sprinkling some
M4 magic dust over it later, but your way seems better I have to
admit.

Huh? Isn't argc always >= 1? Or is it 0 for some weird platform
without the concept of a command line?
