The project you're talking about is using non-portable method of
dealing with pthreads. Pthread interface doesn't specify an internal
structure of pthread primitives, so their actual implementation may
vary (and does vary) between different systems. You should ask
YahooPOPs people to use portable constructs so that their code can be
compiled on any system which supports pthread interface.
