Sure, but then you have to use the -mno-cygwin option to gcc
when compiling, which sometimes can be tricky. So my comparison
above is still valid, and you don't need cygwin to run mingw.

The msys terminal is very nice, and I don't see any reason
to fire up the whole cygwin[1] beast to compile a native
windows app now and then, unless you need something in
cygwin which is not provided by msys of course.

I also think its messy to mix the mingw and cygwin
environments, since they are not compatible. Its easy to
link with libraries of the other type (ie. compiling
with mingw and link with cygwin libraries, or compiling
with cygwin and link with mingw libraries), and then
strange things can happen. Its better to keep the two
environments in separate installations if you can.
At least thats my experience.

No, that would be very strange.

I wouldn't worry about that. Gcc is gcc.
