+        * GCC 3.3.4 Released.
+
+2004-03-02  Gabriel Dos Reis  <gdr@integrable-solutions.net>

+        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.
