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
