Ummm....
    Well, I guess, it should have been "-mno-cygwin" (expanded to "-m
no-cygwin"). This option is available only for the cygwin gcc as is the case
with you.

    I really don't understand from where does the extra blank space come
from? In configure.in, line #15 reads

    CC="gcc -mno-cygwin"

    while line #423 reads

    CFLAGS="$CFLAGS -mno-cygwin"

    which should never expand to "-mno -cygwin". Just cross check whether
it's actually "-mno-cygwin" or "-mno -cygwin".
    Let's see what others have to say!


Happy hacking,
