	* Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
	.word is < -32768 or > 32767.  The -J flag causes the error to be
	ignored.  This is to catch over-sized switches generated by gcc on
	systems which don't support the broken .word hack.
	as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
	write.c (fixup_segment): check for signed .word overflow if
	WARN_SIGNED_OVERFLOW_WORD.
