Thanks for the bug report.

Indeed.
Until a 64-bit port is done, Oaklisp requires 32-bit pointers
I've just push code to error out when it notices "0 byte" pointers.

There is no possibility of compiling Oaklisp on a 64-bit machine without
some compiler option requesting a 32-bit pointer memory model.
I thought GCC used -m32 for this purpose whenever feasible. Ah well.
Perhaps there is an existing autoconf macro,
AX_CFLAGS_32BIT_MEMORY_MODEL or something like that? I poked around but
didn't find anything. I suppose I'll have to break down and write one
myself, casing out on architecture.
You include the magic above for mips64. You wouldn't happen to know it
for other multilib-enabled 64-bit platforms, would you?
(Of course, another possibility would be to simply drop all 64-bit
architectures aside from amd64 and let people use multiarch to install
the appropriate 32-bit package when applicable.)
Cheers,
