Known bug in include/obstack.h (fixed in gcc mainline)

Fixed by replacing include/obstack.h from libiberty master copy (current CVS 
mainline)

Note: 

Suggested fix resolve problem with obstack.h.
But llvm-gcc have another problems with build using CVS mainline GCC.
I attempt find fixes for its.

Can you email me the updated file for obstack.h?  I would be happy to update 
it, but don't have a GCC tree handy.
