Well, no, a cons is not a buffer nor a buffer name.  No surprise that
this causes an error.

The next two forms are a macro expansion and the macro call itself;
they look fine to me.

This next is presumably code from babel.el, which I don't have.  I
guess that the form that produces `tmp' does something different in
GNU Emacs, but what I have no idea.  Can you figure out what this code
is trying to do?

Alternatively, replace it with:

 (let ((current ...))
   (with-temp-buffer
     (mm-decode-coding-region (point-min) (point-max) charset)
     (set-buffer-file-coding-system charset)
     (mm-enable-multibyte)
     (copy-to-buffer current (point-min) (point-max)))

where the ellipsis should be replaced with whatever is there in the
original code, of course.
