	* acgeneral.m4 (AC_OUTPUT_HEADER): Apply Jan 15 fix to

	Rearrange logic: do no tests if $with_x=no; make incl and lib
	tests independent, and distinguish unset from empty.

	* autoconf.sh (undefined macro check): \ sed \s inside "".  If
	grep $name in $infile misses, give error message that there must
	be an Autoconf bug.
