[Bug libc/364] strerror_r does not copy error string to user supplied buffer

["vda dot linux at googlemail dot com" <sourceware-bugzilla@sourceware.org>]

Because I'm tracking down obscure bug in svn (seemingly),
and tracked it down to strerror_r not updating buffer 
and _not_ returning -1.

It _is_ glibc 2.4. Looks like glibc people switched to POSIX version
of strerror_r. See here:

But sometimes it returns >=0, yet buffer is not modified.
