Time to find out why pthread_create() and friends are not being
defined.

First a sanity check:

  nm /path/to/libpthread.a | grep pthread_create

Here is what the output looks on my system:

$ nm /usr/lib/libpthread.a | grep pthread_create
00000eec T __pthread_create_2_1
00000eec T pthread_create

Assuming you get similar output, this command should provide
further clues:

  g++ -static threads_static.c -o threads_static -pthread \
    -Wl,--verbose,-ypthread_create

Ok, that's about the only time when it is reasonable to link -static.
