That sounds fairly straightforward. Do I have to do anything
to prevent the compiler from optimising for the chip it's
compiled on (rather than the target chip)?

I imagine that took a wee while.  The 486 machine's disk
situation is a lot better now than it was, the secondary ATA
disk seems to have about 150Mb of space, none of which is
used at present. It isn't necessarily mounted where it could
be of most use, but that's probably fixable.
