Increase version to 1.2.5 Now should work on Win95 as well Use Tcl_GetUnicodeFromObj in stead of Tcl... Closed-Leaf check-in: 7bb9d6699f user: jan.nijtmans tags: bug-473946

	* generic/configure.in:    Better detection and implementation for cpuid
	* generic/configure:       instruction on Intel-derived processors, both
	* generic/tclUnixCompat.c: 32-bit and 64-bit.
	* generic/tclTest.c:       Move cpuid testcase from win-specific to generic
	* win/tclWinTest.c:        tests, as it should work on all Intel-related
