I am observing strange things while linking boost::thread on a linux  
system with gcc 3.4.6.

If I link an app with
        -L[path to boost.thread] -lboost_thread-gcc34-mt
then it links fine.

If I link with
        [path to boost.thread]/libboost_thread-gcc34-mt-1_36.a
then I get linker errors with unresolved externals to things like:
        pthread_mutexattr_init
        pthread_detach
        pthread_getspecific

I suspect it has to do with dynamic vs. static libraries.  I have two  
flavors built:
        libboost_thread-gcc34-mt-1_36.so.1.36.0
        libboost_signals-gcc34-mt-1_36.a

So I suspect that in the first case I am getting a dll while in the  
second case the static link fails for some reason.  Any suggestions/ 
tips to get the static link to work?
