The code has its own TIME type, which is actually defined to time_t,
but it still used u_int32_t in some places.
In addition, dhclient not only had two separate global cur_time
variables, one of which was defined as u_int32_t and the other as
TIME, but cur_time was sometimes shadowed by local variables, leading
to widespread confusion as to which of these variable was being
referenced.
There is a lesson in here somewhere: a decent compiler with warnings
enabled should have caught all of this long before it became a
problem.
This patch has been submitted to the vendor, but it will likely be
some time before they release a version that includes it.

{ip,udp,tcp} header and return a void * pointing to the payload (i.e. the
first byte past the end of the header and any required padding). Use them
consistently throughout libalias to a) reduce code duplication, b) improve
code legibility, c) get rid of a bunch of alignment warnings.
a short pointer. The previous implementation seems to be in a gray zone
of the C standard, and GCC generates incorrect code for it at -O2 or
higher on some platforms.
Rebind the client socket when we experience a timeout. This fixes
the case where our IP changes for some reason.
Signal a VFS event when NFS transitions from up to down and vice
versa.
Add a placeholder vfs_sysctl where we will put status reporting
shortly.
Also:
Make down NFS mounts return EIO instead of EINTR when there is a
soft timeout or force unmount in progress.
(but keep it conditional on __ISO_C_VISIBLE >= 1999.
Why? Our out /usr/src/contrib assumes it, and more than a few ports have
an autoconf that looks for __va_copy because it is available on glibc.
It is critical that we use it on PowerPC. It generally isn't a problem
for i386 and its ilk because those platforms can get away with cheating
the C standard, using a plain assignment.
hangs due to recent preemption changes. This change appears to remove
the panic that I was running into, but at the cost of increasing
ithread scheduling latency, and as such is a temporary band-aid until
jhb has a chance to resolve the ule<->preemption interaction that is
the source of the problem. If it doesn't fix the problem for others--
sorry!
These trivial implementations are about 25 times slower than
rint{,f}() on x86 due to the FP environment save/restore.
They should eventually be redone in terms of fegetround() and
bit fiddling.
