cc -O -pipe -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes  -c /usr/src/sbin/fsirand/fsirand.c
cc1: warnings being treated as errors

*** Error code 1

Stop.

It compiles just fine on i386 though... I seem to remember something
similar happening with amd... gcc on m68k likes printing these spurious
warnings :)
