(Forgot to cc gnats@, & bugs@ sorry for the noise ...)

My bad, I completely missed the nl_types.h in _catclose.c.

But there's nontheless a problem:

It looks like load_msgcat is leaking FD. It opens
/usr/share/nls/C/libc.cat and right after the mmap(2), the call to
close(2) fails. This doesn't happen all the time though.
