Makes sense. Wow, that's quite a patch.

I'd be tempted to replace the 'char *codeset' fields in the various
locale info structs with integer IDs as well, but the entanglement
with the _*_locale_buf buffers makes that rather complicated. Also,
I'm generally quite concerned about the amount of additional
complexity and indirection being introduced there, but I better take
those concerns to the newlib list.
