Summary: segfaults with nl_langinfo

Initial Comment:
import locale
locale.nl_langinfo(0x20032)

This crashes - no stack trace. Smaller constants work.

The problem is that glibc's nl_langinfo sometimes returns
int values, instead of char*. E.g. 0x20032 is
_NL_TIME_ERA_NUM_ENTRIES, which returns the number of eras.
Use of these constants is not supported, so _locale shall be
changed to verify the arguments to check it is a supported
argument.

Fixed in _localemodule.c 2.26.

_localemodule.c has Martin's name at the top of it, so he
gets this.

This would seem to be a bug in some versions of glibc --
nl_langinfo is setting errno and returning NULL.  Fixed just
over two years ago in glibc CVS, but obviously still "out
there".  Worth working around?  Shouldn't be too hard.
