Can there be a more meaningful error message?

Here are the results:
The usual way (which works with autoconf 2.13)
export CC="gcc -mno-cygwin"
./autogen.sh --with-included-gettext
does not work.
The host system is considered to be a cygwin system and so MINGW32 is
not set to yes by ./configure. 

The thing which works is:
export CC="gcc -mno-cygwin"
./autogen.sh --with-included-gettext --host=i386-mingw32
--build=$(./config.guess) --enable-client=win32

So building freeciv with cygwin is more difficult than cross compiling
it with autoconf2.53. I can live with that.
