OK, that is good to know.  I developed the attached C program that does
the setlocale canonical test.  On Debian Squeeze, I could not see any
change:  if I pass en_US.UTF-8, I get en_US.UTF-8 returned;  if I pass
en_US.UTF8, I get en_US.UTF8 returned.  Can anyone test this and find a
case where the local is canonicalized?  Run it this way:

    $ canonical
    LC_COLLATE = 3
    LC_CTYPE = 0
    $ canonical 0 en_US.UTF8
    en_US.UTF8

We are looking for cases where the second argument produces a
non-matching locale name as output.

I have also attached a patch that reports the mismatching locale or
encoding names --- this should at least help with debugging and show
that a dash is the problem.

No idea.
