Thanks.  In retrospect it was a mistake to append the trailing
newline, I guess.  I installed the following: it differs from your
patch only in adding more commentary.

	* lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
	cross-compiling from cygwin to mingw.
	Reported by Bob Rossi.  This resurrects the 2000-11-30 patch to
	aclang.m4, which was mistakenly removed in the 2001-09-17 patch
	to lib/autoconf/c.m4.
