I thought the right thing to do in this particular situation was to add
a defvar form that read something like this:
(defvar x-resource-name)
Thanks.

That would hide the compilation warning, too -- but if the code actually
ends up being called, it'll bug out. (That's not very likely in this
case, though.)

Hmm, thanks for explaining. But I thought defvar didn't do anything
with variables that are already defined, such as in C code.
Thanks.

They don't. But if you call the code that use those variables (that
aren't defined), the code will error out.

That code in particular can never be called outside PGTK, I think, so I
wouldn't be worried about that.
But thanks for explaining.

But term/pgtk-win is only ever loaded when x-resource-name is defined.
