* 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.
