[boost] threads

Dear William E. Kempf,

I installed the latest version of the boost-1.31.0 on
Win xp pro with  vc7.1 and tried to use the thread
library. 

During the first build of several samples, MSVS(vc71)
gave me a warning about the errors. However I ignored
the errors and select option to proceed(the same
result is in other case). It seems to me the samples
work correctly in spite of errors and warning located
below my message.

I had no warning or errors on the next build of the
same sample at all. 

Would you please tell me what is going on? And how do
I  fix it? 

Thanks

Valery Salamakha
