Do we need to preserve ABI for gconv modules, or are they totally

considering the warning that is issued when you link statically, i'd say the
policy has been that the ABI is private to glibc.  especially since you can't
really link directly against them, and you shouldn't be dlopening them
directly.


Okay, my gconv transliteration module removal patch breaks the gconv ABI.
