Void is well defined and pretty easily portable, though it's true that
many compilers don't fully implement it.  If you write the code
with void, it can be trivially made to work on systems without broken voids
by adding COPTS='-Dvoid=int' to the Makefile -- without source changes.
*That*'s portability...
