Compile it with -DINTEL_32BITS. Put this define in the commands
and commands/ibm makefiles. You have to remember to take it out
when compiling 16-bit commands. It's best to forget about those.

It works well with no special treatment here. I used makefile.st.

I use Gnu cpp but it doesn't quite compile with bcc (due to a
structure return). This is not hard to work around. If anyone does
it, send me a note and I will supply fixes for a couple of Minix
pipe bugs. It's important to use the `-traditional' flag with gnu
cpp when compiling the kernel and when calling it from cppmake.
