It seems to solve it perfectly well. The current binaries are compiled
against 1.4.x, so if GTK is providing a 1.4.x binary, we can tell users
to get it there. What's more, GTK has a single easy to use installer
that inserts registry entries that addpm.exe already detects and
configures Emacs to use GTK libraries if it finds them, vs GnuWin32's
separate installers for each library.

Faced with a choice between 1.4 and an old 1.2 with known security
vulnerabilities, I know which one I'd rather recommend to users.
