Boost::Threads g++ warnings

To compile boost threads with g++ version:
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)

This is not done with the Jam build system, but with
autoconf/automake/libtool.

without warnings and a compile failure I have to do these changes:

Warnings about unused arguments:
