$NetBSD: patch-aj,v 1.2 2010/01/17 08:00:47 dholland Exp $
Patch from Wofgang Solfrank:
"Change the timeout value from 1 usec to 10 msec in the timer thread.
At least with unproven-pthreads, the comment above that is wrong
when stating that a 1 usec timeout would be stretched to the next
system clock tick."
Also, patch out no-longer-supported gcc language extensions.
