[Debian GNUstep maintainers] Bug#633557: lusernet.app: use modern GNU Objective-C API

[Colin Watson]

Package: lusernet.app
Version: 0.4.2-6
Severity: normal
Tags: patch
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu ubuntu-patch oneiric

The following patch converts lusernet.app to the modern GNU Objective-C
API.  Without this, when built with GCC 4.6 we get this compiler
warning:

  Function `objc_lookup_class' implicitly converted to pointer at MsgDB.m:345

... which causes particular problems on certain architectures where
pointers are larger than integers.

This patch is on top of the patch I just sent to fix a build failure
with 'ld --as-needed'; if for some reason you want to apply them in a
different order, it's of course trivial to adjust.

+  * debian/patches/40_modern_objc_api.dpatch: Use the modern GNU Objective-C
+    API.
