Hmm... this surprised me. Mr. Maclean indicated the warnings were level 1
_and_ 2. Builds with bjam do report errors, so the warning level can't be
0. MSDN indicates "Level 2 is the default warning level at the command
line." So I assumed that it must be an RTL issue causing the warnings for
him. However, experimenting with 'bjam -sTOOLS=vc7
-sBUILD="<vc7><*><cxxflags>-W2' does indeed produce the warnings in
question. So it appears that MSDN is wrong, and that level 1 is selected
if none is supplied? I plan to bump the level up in my own set of bjam
tool sets.

As for the warnings themselves... I'm still doing more research just to be
100% sure, but everything I've found thus far indicates you can ignore
these warnings as long as you link against the same RTL in both the
Boost.Threads DLL and the application. After I verify this, I'll remove
the warnings through the use of pragmas.
