Correct. The ARM port was done at the end of 1998.

This is roughly what's happening. However, the constant in question
doesn't come from polymorphic variants, it's just a stack frame size
(1180) that cannot be expressed as an ARM immediate.
I'll try to fix this, however I no longer have access to an ARM machine
(e.g. Netwinder) to test the ARM code generator. If anyone wants to
do beta-testing, just drop me (Xavier.Leroy@inria.fr) a line.
