Use ACK cc and asld to build winiboot and bootlace. Use ACK cc or bcc -0 to
build shoelace. Use any cc to build a native laceup.

The Decus cpp posted the other day is probably OK. There is a cpp in the
archives (I think the same one) ported by Andrew Cagney mainly to compile
Minix under DOS.

I use gnu cpp. This can be compiled with bcc after changing one function to
get around bcc's limit of no structure parameter passing/return. You also
have to split up writes to get around Minix's limit of writing only 7K to
pipes. Finally, it is usually best to give cpp the `-traditional' flag. I
do this by normally executing /lib/cpp which is

	exec /usr/local/bin/cpp -traditional $*

where the real cpp is in /usr/local/bin. This flag must be given to cppmake
too.
