cpp is probably predefining minix as 1. I hade this problem with Gnu cpp
predefining i386 (there is a directory i386 in the 32-bit system makefiles).
For use with cppmake, it is safest not to predefine anything. Note that the
makefile for cppmake itself effectively predefines _MINIX and _V7.

& A last note, when building the 32 bit system, bcc complained about
& redefinition of NULL. I had to change unistd.h and stdlib.h and some
& others from:
& 
& #define NULL ((void*) 0)
& 
& to
& 
& #ifndef NULL
& #define NULL ((void *) 0)
& #endif

The header files with void* must be old - it is spelled consistently as void *
in 1.5.10. The differing white space is not significant to C but unfortunately
the preprocessor does not know that.
