You'll have to drill into this a bit yourself I think. That changeset does
add a fair bit more assembly language to the rombios codebase (particularly
in 32bitgateway.c) but it doesn't look particularly different from the
existing assembly language in rombios.c. Clearly there *is* a difference
though -- perhaps you can narrow down which lines are causing the problem
and tinker with them a bit to see what's causing as86 to barf?

It's definitely odd: unlike gas I don't think there are that many different
versions of as86 to be causing weird differing build-environment behaviours.
