Jake.Stine a628c163d5 w32pthreads:
* Implemented a combination static link and dynamic link system; threads still benefit from DLL-level thread management, but speed-critical actions (semaphore and mutex locks) can now inline their "accelerated" interlocks properly.  Should be a nice speedup.
 * Implemented a highly optimized pthread_testcancel(), that typically performs its test in a single cycle. :)
 * Disabled static mutexes.  They aren't needed in C++ code, and reduce mutex locking overhead nicely.
 * Use intrin.h for Interlocked functions, instead of pthreads' built in ones.
 * Reverted my previous commit, since TLS isn't safe in DLLs.  (oops!)
 * Disabled pthread_spin API, it's not entirely cross-platform and shouldn't be used anyway (bad threading model for modern computing)

pthread_kill (pthread_t thread, int sig)
/*
* ------------------------------------------------------
* DOCPUBLIC
* This function requests that a signal be delivered to the
* specified thread. If sig is zero, error checking is
* performed but no signal is actually sent such that this
* function can be used to check for a valid thread ID.
*
* PARAMETERS
* thread reference to an instances of pthread_t
* sig signal. Currently only a value of 0 is supported.
*
*
* DESCRIPTION
* This function requests that a signal be delivered to the
* specified thread. If sig is zero, error checking is
* performed but no signal is actually sent such that this
* function can be used to check for a valid thread ID.
*
* RESULTS
* ESRCH the thread is not a valid thread ID,
* EINVAL the value of the signal is invalid
* or unsupported.
* 0 the signal was successfully sent.
