Ah, I hadn't noticed what the dummy definition of setlocale was.

For Emacs, the `free' in this hunk should be `xfree', but as far as I
remember, gnulib wouldn't accept my xfree, so Emacs will need to
maintain a separate copy.

[The stuff Emacs has at the end of files like this

/* arch-tag: 2b37a242-6289-41f4-8cd5-0e73fd615db1
   (do not change this comment) */

presumably also prevents merging with gnulib, whatever it's there for.]
