  "stdcall" is already used in Claw.  It works on Apex, Gnat, ObjectAda,
and Janus.
  Claw uses 'access', not system.address, which is not, in fact, always
the same thing as a C pointer.

  I really can't understand why, given the examples of
System.Address_To_Access_Conversions, Interfaces.C.Strings,
Interfaces.C.Pointers, and a given a demonstrated ability to move
comfortably among different abstractions, anyone would use such a low
level, implementation defined thing as System.Address.  Given the
frequency with which it's done in c.l.a. postings, I guess it seems
reasonable to more than a few people.  #.#
