[patch] Fix expect build under Cygwin + Tcl/Tk 8.3

[Mo DeJong <supermo@bayarea.net>]

Greetings.

The current CVS version of expect does not build correctly under Cygwin. The root of the problem is that expect is searching for a tclConfig.sh file in tcl/unix when it should be looking in tcl/win. The following patch fixes the problem by updating the m4 macros used by the expect build.

Note: This patch was extracted from a larger patch posted to the Insight list but it does not depend on the other Cygwin related changes to Tcl.

	* aclocal.m4 (CY_AC_PATH_TCLCONFIG, CY_AC_PATH_TKCONFIG,
	CY_AC_PATH_ITCLH): Update macros that search for tclConfig.sh
	and tkConfig.sh so that they also check the win/ subdirectory.
	Update macro that checks for itcl.h so that it looks in
	itcl/itcl/generic instead of itcl/src. These updates
	are needed to get things building correctly under Cygwin
	gcc and Tcl/Tk 8.3.
 	* configure: Regen.
