	* unix/tcl.m4:        [Bug 3511806] Compiler checks too early
	* unix/configure.in:  This change allows to build the cygwin
	*                     and mingw32 ports of Tcl/Tk to build
	* win/tcl.m4:         out-of-the-box using a native or cross-
	* win/configure.in:   compiler.
	*                     (autoconf has to run yet!)
