RE: [boost] VC7/Threads Warnings

For your information I also get these warnings when building using bjam.

As you mention below - ignoring the warnings seems OK in my code (but it
is simple stuff).

Is it possible to create a static library? I suspect that the defines
prevent this. This was possible in version 1.29. Obviously this is not
for the monitor but when not using the monitor it would be nice to have
a static library to link in. Then I don't have to worry about making
sure the dll is present.

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.
