Nope. because an autoconf script for mingw32 'build' may expect cp to be
'copy', sh to be cmd.exe and further stuff that will break or misbehave
on cygwin.

 $ env CC=mgcc ./configure --host=i686-pc-mingw32 --build=i686-pc-cygwin
is acceptable.

See above why it doesn't. mingw != cygwin :}.

Well.. I came in the thread late, so I get to say, 'huh, what, waddya
mean?'.
