Also, with autoconf I often end up needing to set CC and CFLAGS via

Side note: With non-ancient autoconf, CC ought to be retained by
config.status --recheck.

And I think that's a nice feature of the configure system.
Oh - thanks. Are those stored easily visible somewhere as well?
One of the more common usecases for me is to rerun configure with the same
set of configure options, but adjusting them slightly (for build trees
that I haven't built recently). With libav, I edit the top of config.mak
and rerun "make config", while with autoconf I check the head of
config.log and rerun configure with those, but I don't remember seeing CC
there (although perhaps my autoconf has been too old).
