Bug#751857: [PATCH] private-update.cc does not compile when --disable-nls is used

[Fredrik Fornwall <fredrik@fornwall.net>]

Package: apt
Version: 1.0.4
Severity: normal
Tags: patch

When --disable-nls is given to configure, apt-private/private-update.cc
does not compile due to calling ngettext(), which buildlib/apti18n.h does
not define when USE_NLS is undefined.

Looking at other files the P_ macro (which apti18n.h do define) is used,
so I guess that the correct fix is to change private-update.cc to use that
one (instead of adding a ngettext macro to apti18n.h).
