Modified files:
	cm3/m3-libs/m3core/src/thread/WIN32/: ThreadWin32C.c 

Log message:
	make it work with more compiler/header versions
	consider moving initialization and cleanup into DllMain
	in particular, this lets us propagate failures, which are possible
	but the problem is that executables don't have DllMain (tls callbacks?)
