 	* ptw32_threadStart.c (ptw32_threadStart): Routine no longer attempts

 	to pass [unexpected C++] exceptions out of scope but ends the thread

 	normally setting EINTR as the exit status.

+	* ptw32_throw.c: Fix C++ exception throwing warnings; ignore

+	informational warning.

+	* implement.h: Likewise with the corresponding header definition.
