Hmm... it doesn't seem to work.  The function declaration is:

  extern inline int testandset(int *spinlock)

but I can't link to it, even though it appears in the name list:

  [jsturm@toronto jsturm]$ nm /lib/libpthread-0.8.so | egrep testandset
  00008d78 t testandset

it's declared similarly for other architectures.
