CVS commit: src/sys/sys

[Havard Eidnes <he%netbsd.org@localhost>]

Module Name:    src
Committed By:   he
Date:           Thu Jun  2 14:31:38 UTC 2005

Modified Files:
        src/sys/sys: cdefs.h

Log Message:
Add an __UNVOLATILE() macro.  It should be used with caution, but
it is required to use this whenever you want to pass a pointer to
volatile data e.g. to memset().  This allows us to still compile
files doing such things with -Wcast-qual and get the rest of the
code checked under that option.

Based on suggestions from tron and christos.
