Should I be able to build cross gcc 4.x on Cygwin?

Cygwin imposes a sometimes significant performance penalty as a tradeoff
for being able to use POSIX apis on a system where they don't exist, so
this is expected.  Particularly, the fork/exec sequence that is at the
heart of POSIX process creation is extremely slow under Cygwin, and
shell scripts that spawn many subprocesses this way suffer the most.

That is always what I've used (at the toplevel configure) and it seems
to work fine.
