	* win/tclWin32Dll.c: Rewrote the Windows stack checking algorithm
	to use information from VirtualQuery to determine the bound of the
	stack.  This change fixes a bug where the guard page of the stack
	was never restored after an overflow.  It also eliminates a nasty
	piece of assembly code for structured exception handling on
	mingw.  It introduces an assumption that the stack is a single
	memory arena returned from VirtualAlloc, but the code in MSVCRT
	makes the same assumption, so it should be fairly safe.
