Bug#710387: xbs: FTBFS with clang instead of gcc

[Sylvestre Ledru]

Package: xbs
Version: 0-8
Severity: minor
Usertags: clang-ftbfs

Hello,

Using the rebuild infrastructure http://buildd-clang.debian.net/, your package 
fails to build with clang (instead of gcc).

You can see the full log here:
http://buildd-clang.debian.net/fetch.php?pkg=xbs&arch=amd64&ver=0-8&stamp=1366802978

The attached patch fixes it.

Thanks,
Sylvestre
