It'll probably be the same problem afflicting other vendors compilers
-- the DEC UNIX and Sun Workshop compilers both can't compile this
function (delayIdPtrHashCmp).

The code is trying to do arithmetic on pointers to void. This works
under GNU C, because GNU C specifically defines sizeof(void) to be
1. sizeof(void) is undefined on these other compilers however and thus
this won't work.

If you can somehow convince your compilers to let you do this kind of
pointer arithmetic (via a command line option, probably), then you
might coax this into working. Otherwise, you'll need to use gcc/egcs
for now.

Cheers,

Chris
