Upon closer inspection, builtin_define_std will actually surround the macro with
leading and following __'s, if the macro is in the user namespace:

  /* If it was in user's namespace...  */
  if (p != buff + 2)
    {
      /* Define the macro with leading and following __.  */

The attached patch is against the 3.4 branch, and cleans up a couple of
testcases as well.  It does what you suggested-- use __ppc for vxWorks, and
change PPC to __PPC__.

   * longlong.h: PPC macro cleanup (fixes vxWorks targets)
   * gcc/testsuite/gcc.dg/20020103-1.c: PPC macro usage changed to __PPC__
   * gcc/testsuite/gcc.dg/20020919-1.c: Same as 20020103-1.c
