tcl8.4.1 - tclWinInit - AppendEnvironment()

[Patrick Samson <p_samson at yahoo dot com>]

This function was designed at a time when the
parameter 'lib' was fed with a value such as
"lib/tclX.Y", so there is two times a "lib + 4"
pointer to extract the "tclX.Y" part.

But the value has changed to "share/tclX.Y" in
TclpInitLibraryPath(), and now lib + 4 points to
"/tclX.Y", which is of no use !

The caller and the calling should be accorded.
As "lib + a number" is a poor coding design (this
issue shows how fragile it is), I suggest to change it
entirely to a more robust one (RedHat/Cygwin people to
inform developers at sourceforge?).


I also have a doubt about this part of code, at the
end:
	} else {
	    objPtr = Tcl_NewStringObj(buf, -1);
	}
	Tcl_ListObjAppendElement(NULL, pathPtr, objPtr);

In my understanding, it means that the same object is
appended a second time. Am I wrong?
