System: NetBSD arioch 1.1_ALPHA NetBSD 1.1_ALPHA (ARIOCH) #0: Wed Dec 13 03:23:51 EST 1995 roland@arioch:/usr/src/sys/arch/i386/compile/ARIOCH i386


>Description:

For the i386 port, I could not compile a kernel with HZ defined.
(I am not sure if one is supposed to, but I wanted /kern/hz to be
the speed of my processor, not 100.)

The problem is that microtime() is defined in sys/time.h to be of
type void, and in arch/i386/i386/machdep.c, if HZ is defined,
microtime() does not have a type and therefore defaults to int.

>How-To-Repeat:

Put:

options  HZ=80

in your config, and 

$ config ./ARIOCH; cd ../compile/ARIOCH; make depend && make

>Fix:

Add a void in front of microtime.
