* generic/tcl.h: Skip Tcl's define of CHAR,

	SHORT, and LONG when HAVE_WINNT_IGNORE_VOID
	is defined. This avoids a bunch of compiler
	warnings when building with Cygwin or Mingw.
	* win/configure: Regen.
	* win/configure.in: Define HAVE_WINNT_IGNORE_VOID
	when we detect a winnt.h that still defines
	CHAR, SHORT, and LONG when VOID has already
	been defined.
	* win/tcl.m4 (SC_LOAD_TCLCONFIG): Subst the
	TCL_DEFS loaded from tclConfig.sh so that
	Tcl defines can make it into the Tk Makefile.
