Hey, remember back when Russell Mok said:

That fixed the wchar_t stuff. I still needed to hack the Jam file so
that the gcc-Link-action action would link .so files with -pthread.

I am sure there is a better way to do that, just not sure where in the
gcc-tools.jam file would be the best place.

I am still getting these strange link errors:
