* generic/tkMain.c (Tk_MainEx): replicate macosx-specific code from

	TkpInit() that ensures the console window appears when wish is started
	from the OS X Finder (i.e. with stdin == /dev/null), jeffh's 2006-11-24
	change rendered the corresponding code in TkpInit() ineffective in wish
	because Tk_MainEx() sets tcl_interactive before calling TkpInit().

	* generic/ttk/ttkGenStubs.tcl (new): add ttk-specific genstubs.tcl from
	* unix/Makefile.in (genstubs):       tile and run it from 'genstubs'
	target, restores ability to generate all of Tk's stub sources.

	* generic/ttk/ttkTreeview.c: #ifdef out unused declaration.

	* macosx/tkMacOSXDebug.c (TkMacOSXGetNamedDebugSymbol): add fix for
	libraries loaded with a DYLD_IMAGE_SUFFIX.

	* macosx/Wish.xcodeproj/project.pbxproj: ensure gcc version used by
	* macosx/Wish.xcodeproj/default.pbxuser: Xcode and configure/make are
	* macosx/Wish-Common.xcconfig:		 consistent and independent of
	gcc_select default and CC env var; fixes for Xcode 3.0.

	* unix/tcl.m4 (Darwin): s/CFLAGS/CPPFLAGS/ in macosx-version-min check.
	* unix/configure: autoconf-2.59

+#
+# CHANGES: 
+#	+ Remove xxx_TCL_DECLARED #ifdeffery
+#	+ Use application-defined storage class specifier instead of "EXTERN"
+#	+ Add "epoch" and "revision" fields to stubs table record
+#	+ Remove dead code related to USE_*_STUB_PROCS (emitStubs, makeStub)
+#	+ Second argument to "declare" is used as a status guard
+#	  instead of a platform guard.
+#	+ Use void (*reserved$i)(void) = 0 instead of void *reserved$i = NULL
+#	  for unused stub entries, in case pointer-to-function and 
+#	  pointer-to-object are different sizes.
+#	+ Allow trailing semicolon in function declarations
+#	+ stubs table is const-qualified
+#
