So that enum would need to be placed in the the various _local_bufs
then, which means it would need to appear in binary form in the locale
file format on non-Cygwin systems. Can we do that?

Also, I belatedly realised why the charsets might be represented as
strings in the first place: because charset definitions could be read
from disk rather than being hardcoded as they are in newlib. Should I
still pursue the enum idea or go back to your idea of passing a
pointer to the relevant charmap table (if any) around?

Thanks for the patch.
