Should be fixed in SVN.

Well, ERANGE may also not be defined everywhere. I just #ifdef EOVERFLOW to -1 
(just needs to be not 0).

Fixed.

http://www.cl.cam.ac.uk/~mgk25/ucs/langinfo.c might have a solution for this.  
If you can test it and send a patch (that only changes things on OpenBSD), 
I'll be happy to integrate it.

Right.

Strange.  Not sure what a good fix for this would look like.  If you have any, 
please let me know.  The other fixes are in SVN #2666 (and will be in the 
next LE release).  I've also added the various "unresolved" issues to the 
PLATFORMS file as comments about LE on OpenBSD.

Cheers!
