Thank you all for your prompt responses. I comment further below:

I already was using the multithreaded libraries. If I had select
single-threaded libraries, the boost::thread hpp files would have
generated a compiler error.

I had already enabled RTTI.

This was already blank.

This was interesting. On Visual C++ 6.0, it did not make any difference
to the linker output. On Visual C++ .NET, it removed all the 'multiply
defined symbol' errors except for those relating to three basic_string
constructors and basic_string::c_str(). (It solved MOST of the problem,
but didn't take care of everything.) However, if I exclude the main C
runtime library files from my build as you suggest, it seems like I
would run into more problems later on when I try to use standard C
functions.

Again, my problem when linking with the library in VC6 is that
libboost_thread.lib(exceptions.obj) has one unresolved external symbol
for basic_string::basic_string(char const *).

I'm still flummoxed. If you have more ideas, I would really appreciate
them.

Thanks,

Jonathan
