   1 The handling of varargs is platform-dependent.  Assar Westerlund
   2 stared at the problem for a while and deduces the following table:
   3
   4 vers / compiler         cc              gcc
   5 ----------------------------------------------------------------------
   6 1.3                     a0, offset      __base, __offset
   7 2.0                     _a0, _offset    __base, __offset
   8
   9 The current code should handle both cc and gcc versions, provided
  10 you configure for the correct compiler.
