Thanks for the report. There's a couple things wrong that I can see 
right off the bat. The first param should indeed be "pthread_t", and the 
Cygwin code that implements the function should treat that first param 
as a thread id. Currently it's treated as a 'pthread_t *' to match the 
prototype.

I'll work on a patch for these issues.
