Does Shareware X-Chat for Windows Violate the GPL?

pc486 writes "The popular IRC client X-Chat has recently come under criticism as to whether or not the new shareware Windows version of the IRC client violates the GPL. All sorts of points are being persued, such as pure GPL Gettext linking, gtk translation worries, copyright issues, who's code is what and more." This is a complicated tale of GPL licensing, so beware.
