Sorry, I should've mentioned that I'd done that. For the moment I've just
gone the "all internal" route (for all the available ports, at least).

Ah, I NOW see there's a unix/src/vm/ - I was looking in unix/vm/.

OK. Does it matter that I'm running VMMaker on a Windows machine and then
copying the resulting src/ over to a FreeBSD machine? (I'm thinking in
particular of line endings.)

I've tried various things, and had various errors preventing compilation.

I thought then I'd try compile the 3.10-4 straight as-is. This should
generate a 32 bit VM, yes? At least, it looks that way judging from the
enormous number of warnings complaining about size differences in casts.
Anyway, after a lot of sweating and consulting my local gcc guru, the
following incantation resulted in a fully-compiling 32 bit VM:

  mkdir bld
  cd bld
  ../platforms/unix/config/configure CPPFLAGS=-I/usr/local/include
LDFLAGS="-L/usr/local/lib" --without-npsqueak
  make
  sudo make install

I'll try that out shortly with a Seaside image.
