Thanks. Is someone willing to commit them now they have been accepted? I 
am attaching them as a single patch and copying the changelog entries here 
for convenience (I wrote the date of Monday because it looks like a day

include/ChangeLog:

2011-09-26  Ulrich Drepper  <drepper@gmail.com>

 	* obstack.h [!GNUC] (obstack_free): Avoid cast to int.

2011-09-26  Marc Glisse  <marc.glisse@inria.fr>

 	* ansidecl.h (ENUM_BITFIELD): Always use enum in C++
