I thought it was the .el files themselves that were complaining, but
poking at it a bit more, it's a warning when generating the .el files
from .wy files, so the warnings seem correct, indeed.

Yup.  It's this code:

  (defmacro latin-ltx--define-rules (&rest rules)
    (load "uni-name")

There's no comment about why, but it's pretty obvious when looking at
the file itself -- it has no `provide'.  Is that an oversight or is it
meant to be that way?  These files are all autogenerated...

Perhaps just add a NOMESSAGE parameter to that load?

OK; I'll silence that message (when there are zero conflicts).
