This file? Sorry, but I have little CVS experience.
http://cvs.sourceforge.net/viewcvs.py/*checkout*/boost/boost/libs/thread/src/mutex.cpp
http://cvs.sourceforge.net/viewcvs.py/*checkout*/boost/boost/libs/thread/src/mutex.cpp?content-type=text%2Fplain&rev=1.11.4.4

It does not do what I have suggested. try_mutex still uses a real
mutex instead of a CRITICAL_SECTION on Windows NT.

I did not suggest to use a CRITICAL_SECTION when not supporting the
trylock operation, this is already done. I suggested to check at
runtime the operating system version and choose the best option.
