I created one of them, but as far as I can tell it didn't pick it up.

Sounds good.

Yes.

Well, below are some of the changes I made today to get it to go
past the various errors.  Probably the most interesting was this
one:

! #define BIG_ENDIAN 1
! #define LITTLE_ENDIAN 2
! #define BYTE_ORDER 1

I don't have a sys/param.h and so I just stuck those in somewhere
that it seemed to be looking for, so that it didn't come up and say
that it couldn't determine the endian order.

It seemed to try very hard to stick in sys/types.h and sys/time.h
and I'm not sure how well I got around that.

It also seemed to execute /bin/as at one point instead of my
dummy cross-assembler.  I'll try to figure out what the logic
is tomorrow.

Note - all this is on 3.4.6.

BFN.  Paul.
