/*
* sehsub.c

* In an attempt to see what might be going on inside CRTDLL, this program
* walks the exception list after creating a new thread with _beginthread.
*
* It turns out that _beginthread DOES install an exception handler, as
* expected, but this handler is NOT exported by CRTDLL (it is certainly
* not _except_handler2 or _XcptFilter)... an odd and unpleasant turn of
* events.
