It's turning off threading support because it thinks your libstdc++ is built 
single threaded: however I have a suspicion this is may be due to a bug I 
fixed a while back - basically it means that if you configure gcc 
with --enable-threads=posix rather than --enable-threads=default then our 
config doesn't correctly detect that case (in case you're thinking "but 
they're the same thing!", they're not at least as far as the macros set by 
libstdc++ are concerned).

Anyway can you try replacing boost/config/stdlib/libstdcpp3.hpp with the 
current cvs version (attached) and see if that fixes things?

John.
