Bug#812148: vftool: FTBFS with clang instead of gcc

[Arthur Marble]

Package: vftool
Severity: minor
Tags: patch
User: pkg-llvm-t...@lists.alioth.debian.org
Usertags: clang-ftbfs

Hello,

Using the rebuild infrastructure, your package fails to build with clang
(instead of gcc).

Detected this kind of error:
http://clang.debian.net/status.php?version=3.6.0&key=FUNCTION_RETURNS_VALUE

Full build log is available here:
http://clang.debian.net/logs/2015-03-25/vftool_2.0alpha-4.1_unstable_clang.log 


I have attached a patch to fix this error.

Regards,
--Arthur Marble
