* win/configure: Regen.
* win/configure.in:
* win/tclWin32Dll.c (TclpCheckStackSpace): Rework
the SEH exception handler logic to avoid using
the stack since alloca will modify the stack.
This was causing a nasty bug that would set the
exception handler to 0 because it tried to pop
the previous exception handler off the top of
the stack.
