Fix mingw build problems and compiler warnings.

	* generic/tcl.h: Add if defined(__MINGW32__)
	check to code that sets the TCL_WIDE_INT_TYPE
	and TCL_LL_MODIFIER.
	* generic/tclClock.c (FormatClock): Don't
	define savedTimeZone and savedTZEnv if
	we are not going to use them.
	* generic/tclEnv.c: Add cast to avoid warning.
	* win/tclWinChan.c: Use DWORD instead of int
	to avoid compiler warning.
	* win/tclWinThrd.c: Only define allocLock,
	allocLockPtr, and dataKey when TCL_THREADS
	is defined. This avoid a compiler warning
	about unused variables.
