+	When using Cygwin, in spite of all their efforts, it may happen
+	that `confestval' be read in binary mode.  The shell then fails to
+	properly strip the \r\n.
+	Reported by Lars J. Aas.
+
+	* aclang.m4 (AC_LANG_INT_SAVE): Don't add any trailing new line,
+	and close the file.
+	Suggested by Peter Eisentraut.
