Thanks for the helpful list.

sys_now() should be defined in one of the unix port (architecture
specific files), but doesn't seem to be.  I'm not sure why not.  It only
seems to be used in the delif.c file, which is not necessary for most
people - I think this just simulates a link of a certain delay.  Try
omitting that file and see if it helps.  Otherwise take a look to see if
there are other uses of sys_now in the contrib/ports/unix - I don't have
a searchable up to date copy of this to hand.

Thanks
