I do not understand the comment about GCC for AIX setting GXX_WEAK consistently.
    The value is set by GCC itself, not overridden by AIX.

GXX_WEAK is defined by c-cppbuiltin.c:

      if (flag_weak && SUPPORTS_ONE_ONLY) 
        cpp_define (pfile, "__GXX_WEAK__=1");
      else
        cpp_define (pfile, "__GXX_WEAK__=0");

and depends on SUPPORTS_ONE_ONLY, not just weak support.  I will test if setting
MAKE_DECL_ONE_ONLY works on AIX.
