There will be some differences starting the next release. I
just put the finishing touches on thread-safe C++ exceptions
for Mingw, and that just won't work for "stock" Cygwin. Of
course, if you don't specify -mthreads option (which defines
-D_MT and adds in the thread-safe helper library), it'll be
the same.

Actually, there are other problems with this setup besides the
quoting issue -- the pathnames have to specially handled by
the driver before passing it on for example. UWIN folks do
this to drive MSVC and there's quite a bit of work to be done
(and I can still break it at will). If you can live with a
little slowdown due to Cygwin overhead, why not just use a
Cygwin hosted Mingw targeted toolchain (just install it somewhere
else, and use PATH to switch to it)? As you can probably guess
already, I have just the setup. In fact, I'm contemplating
packaging it up (which takes a finite block of my time, hence
the contemplation ;-) and putting it up for ftp.

Hey, I know of someone (trying to) build Linux kernel under Cygwin.
so there ;-)
