I think the opposite is the case.  collate.c was changed to _not_ call
err/warn.  The change isn't quite right.  err() writes to stdout while
__collate_err() writes to STDERR_FILENO.  There is a difference if
stderr is buffer.  stdio uses special code to avoid this bug for
perror().  It should use and export a general function __write_stderr().

I'm running the library from a couple of days ago and have some locale
changes but don't have the linkage problems.

They are in the user namespace, like about 90% of the names in libc.
