I guess I never tried.  I did all the development on PC-IX.  But I have an
idea what the problem might be.  For long and complicated reasons, the
MINIX C compiler effectively ignores static declarations.  Thus if you
have a declaration
static int x= 1;
that appears in two files, when you link them you will get multiply defined
symbols.   Take a look at which symbols are multiply defined and see if this
is indeed the problem.  If so, the simplest fix is to systematically change
the conflicting names to nonconflicting names.  It is unfortunate that static
is ignored, but that is a long story and it is not easy to fix.
