Hmpf.  Nowadays AM_CYGWIN just expands to AC_CYGWIN, which causes
$CYGWIN to be set.  The latter is probably a bad idea for other reasons
(Cygwin AFAIK uses the variable for other purposes), but at least one
macro in Autoconf's fortran.m4 still seems to make use of $CYGWIN.  It
should at least also be fixed to use $host_os instead.

Thanks,
Ralf
