[PATCH] Fix nl_langinfo binary compatibility

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

nl_langinfo is not binary compatible with glibc 2.1.
The reason is that CODESET used to be 14 and now is 11. I've checked the
rest of the documented nl_langinfo arguments and they should be ok.
With this patch (and the two I've already sent) JDK finally runs.

2000-07-17  Jakub Jelinek  <jakub@redhat.com>

	* locale/nl_langinfo (__nl_langinfo): Renamed from nl_langinfo.
	(__nl_old_langinfo): New.
	* locale/Versions: Add nl_langinfo@@GLIBC_2.2.
