I can confirm that $march is breaking things on my Mac; with it, I get
f2cFortran, whereas without it I get pgiFortran. So I think that, since
it breaks things, it should probably be killed, as you say, and its
functionality put into CFLAGS, FFLAGS, etc.

This, of course, will cause its own breakages, to the extent that
CFLAGS, FFLAGS and their ilk aren't consistently observed. Do you have
any thoughts on why that is, and whether it should also be fixed?
