Define FD_SETSIZE on Cygwin regardless of XWin DDX 

All DDXs segfault on Cygwin unless -DFD_SETSIZE=256 is set, so make sure
we do so whether or not we are building XWin.

FD_SETSIZE must be at least XFD_SETSIZE for uses of select() to be correct.
The Cygwin default is only 64, so it must be increased to 256
