[Gm2] fixed: procedure type and unbounded arrays

[Gaius Mulley]

Hi Jim,

I've just fixed the bug which you reported a while ago which
occurred with the following declaration:

  TYPE
     proc = PROCEDURE (VAR ARRAY OF REAL) ;

  VAR
     p: proc ;
     a: ARRAY [1..10] OF REAL ;
  BEGIN
     p := foo ;
     p(a)
  END

I'll now rebuild the gm2 tarball from the latest CVS.  Many thanks
for the bug report and test code, very useful!

regards,
Gaius
