Actually, the correct way to do it in egcs/gcc2.8 is to kill the <stdio.h>,
too.  "system.h" includes "auto-host.h", which has knowledge of what sysem
includes are there.

As posted in the updates, if you add -Wno-uninitialized to the warns list,
this will be OK.  Not all of these warnings are appropriate or correct.

Different methods of doing things, and different optimizations and levels of
inlining.  Did you compile with just the default of -O?
