If before, you need the patched version of the libc_r code to have any chance of it working at all. 3) Is he using C++? If so, he must use FSF g++ 2.8.x or better with Jeremy's patches to libgcc.a to make exceptions work with threads (the patches were committed to the g++ port, I believe). 4) Is he depending on the C++ STL? If so, he needs the one from the Moscow Center for SPARC Computing, and he needs some additional patches (that haven't been committed, since STL is not widely supported in FreeBSD) to make it work with a Draft 4 pthreads (specifically, STL assumes that you can statically initialize mutexes, which is wrong).
