glib + foo + bar + ...

If this sort of expansion were to occur, I'd suggest we take the
split-setup option and have a bootstrapping setup that is essentially
what we have today, but is only run once - ever. Then after that a
maintenance setup that is able to use cygwin linked tools.

Agreed.

I recall Danny talking about a gcc v 3.1 for April, but I'm not sure if
he meant as a cygwin package or as something else...

Yup. In fact gcc -mno-cygwin is close enough that automake won't be
confused... as long as it's told --host= :}.
