This should be a static_cast. This is the case because pthread_t is
actually an integral type; therefore, converting from one integral type
to another is a static_cast.
On my machine (i386/sid and i386/experimental), the following is the
type of pthread_t:
typedef unsigned long int pthread_t;

You are also neglecting to return a value here. You must always return
a value in a non-void function.
