[boost] Bug&Patch in thread lib using Carbon Multiprocessing API

Hi,
Hope it is appropriate to post this here. I'm sorry if it is not.

Trying to compile the thread library on the mac I have found some 
errors that keep it from compiling
under the Carbon MultiProcessing api.

There are some wrong function names in the mac implementation and one 
or two missing includes
in thread_cleanup.hpp and thread_cleanup.cpp (see attached diffs)  so 
that current stable package
won't compile. The boost::thread::sleep(xt) function does not sleep 
properly (it wakes up right away)
i tracked the error down to the following call (in 
boost/libs/thread/src/thread.cpp)

AbsoluteTime sWakeTime(DurationToAbsolute(lMicroseconds));

the DurationToAbsolute() function does not return the proper value
replacing it with
AbsoluteTime sWakeTime = AddDurationToAbsolute(microseconds * 
kDurationMicrosecond,  UpTime());

fixes this bug

under mac os 9 there is an assert that fails when running the 
condition.hpp
a call to MPCreateSemaphore() with ULONG_MAX results in an error.
a change from ULONG_MAX to LONG_MAX solves this problem

tested on mac os x 10.2.2 and OS 9.2.2

regards arnold
