   I'm looking at an Ada 95 compiler manual that says its Ada
"Access a_type" maps to "*a_type".  It also says:
"System.Address for Windows NT compilers is 48 bits, including the
segment.  Most 32 bit C compilers cannot use the segment information.
If your compiler can, the declaration would likely be 'far *a_type'.
Otherwise ... pass the (offset component) as '*a_type'.  That will
work only if the address has the same segment as your program."
   We've found in CLAW, which of course is in the business of
talking to C (Windows), a rather modest need for "void".  A quick
scan shows 63 SLOC containing the words Void or LPVoid, out of
about 125 KSLOC.  YMMV
