_configure.bat_ --no-cygwin exists, but because I don't use configure.bat, I
didn't notice it. I'm building Emacs using the usual autoconf machinery and
bash. I'd like to make it possible to cross-compile an NT-native Emacs in the
Cygwin environment using the autoconf machinery.

By the way: -mno-cygwin hasn't worked for a few years now. The Cygwin people now
recommend using a real cross-compiler to compile for MinGW --- e.g.,
i686-w64-mingw32-gcc.

If I had my way, we'd drop configure.bat entirely and always build NT-native
Emacs by cross-compiling from Cygwin.
