You must be kidding. It's a pari issue (and, incidentally, gap too)
because of pari's well known bogus requirement on
sizeof(void*)==sizeof(long). Any ABI which has this is a no-go for
pari. x32 is one of them, Torbjorn named a few more, I think this
applies to win64 too. If your point is that debian is the only
multi-arch distribution which has to care about this, then maybe you
can say it's "purely" a debian issue. But I would not buy such an
audacious statement.

On the other hand, I understand that gmp does fine on the x32 ABI (see
messages in January this year on gmp-devel), so the present discussion
is going off-topic as far as gmp is concerned.
