Actually, the configure_at already correctly recognizes the presence
of the X11 libraries in /usr/lib with no problem. Now, for the
'-DSYSV' part, it is included for all "systems without <sys/dir.h> but
with <dirent.h>", which includes cygwin. I guess I could just add
another if there, so that it only adds -DSYSV if it is *not* cygwin,
but I don't know what effect that will have on older cygwin
