+
+	PR bootstrap/14348
+	Backport
+	2003-10-22  Joseph S. Myers  <jsm@polyomino.org.uk>
+	* obstack.h: Merge the following change from gnulib:
+	2003-10-21  Paul Eggert  <eggert@twinsun.com>
+	* obstack.h (obstack_1grow_fast): Properly parenthesize arg.
+	(obstack_ptr_grow_fast, obstack_int_grow_fast):
+	Don't use lvalue casts, as GCC plans to remove support for them
+	in GCC 3.5.  Reported by Joseph S. Myers.  This bug
+	was also present in the non-GCC version, indicating that this
+	code had always been buggy and had never been widely used.
+	(obstack_1grow, obstack_ptr_grow, obstack_int_grow,
+	obstack_blank):
+	Use the fast variant of each macro, rather than copying the
+	definiens of the fast variant; that way, we'll be more likely to
+	catch future bugs in the fast variants.
