Linking in support for the internal programmer doesn't make sense if you only need hardware (ioport, memory) access. Split internal.c into internal.c and hwaccess.c.
Note: This patch was created by "svn cp internal.c hwaccess.c" and then removing stuff from both files. That's why you can't apply the patch as-is before running the svn cp.
