N.B. There are 32-bit compilers running on 64-bit MacOS.

Heap compiles and runs on MacOS X 10.5.3 here, using Drew Reynolds' latest
64-bit compiler (which has a few other problems, however):

% g heap.adb 
gcc -c -gnat05 heap.adb
gnatbind -x heap.ali
gnatlink heap.ali

% ./heap
  536870912

% g -v

GNATMAKE  4.4.0 20080329 (experimental) [trunk revision 133715]
