size of the binaries has low priority. Functionality and stability is much
more important. And comparing size of binaries without smartlinking also
doesn't give an indication of the real size of code required by the
program.

i_beos.pas misses the extradefines : 'UNIX;HASUNIX';

But that will maybe trigger a lot of new errors because of the Unix redesign.
