commit 39b1f6172a2f9ddc74a8f82d6e84dd13b22dbaf2
Author: Peter Collingbourne <pcc@google.com>
Date: Wed May 15 20:28:08 2013 +0200
Move _obstack_compat out of common
it is impossible to create an alias of a common symbol (as
compat_symbol does), because common symbols do not have a section or
an offset until linked. GNU as tolerates aliases of common symbols by
simply creating another common symbol, but other assemblers (notably
LLVM's integrated assembler) are less tolerant.
