Search for x32 on LWN to see what I mean. IIRC, the x32 ABI was
specified by Intel for use on certain embedded systems. It is
questionable there are any benefits for standard 84 bit CPUs.

Which defines the amd64 ABI and not the x32. That ABI means that an
LONG is 64 bit and not 32. As I said it will likely work to define the
MPI limb size to 64 bit instead of directly to "unsigned long". However
we are mixing two ABIs here which is not a good idea unless it can be
proofed that there are no problems. And as you reported there are
problems mixing the two ABIs.
What about using "./configure --disable-asm" as a workaround?
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
