[PATCH] non-GNU C++ compilers

[Marc Glisse <marc dot glisse at inria dot fr>]

Hello,

this helps C++ compilers that do not define __GNUC__ compile gcc.

Bootstrapped:
1) CC=gcc with --disable-build-poststage1-with-cxx
2) CC=suncc

The second one required a fix for PR49907. I didn't build with sunCC 
simply because it requires several more patches.

Issues were discussed there:
http://gcc.gnu.org/ml/gcc/2011-07/msg00523.html
http://gcc.gnu.org/ml/gcc/2011-08/msg00006.html

Note that I can't commit.

	* include/ansidecl.h (ENUM_BITFIELD): Always use enum in C++
	* include/obstack.h (obstack_free): Cast to char* instead of int
