hugin build error with gcc-4.7

[Andreas Metzler]

Hello,

hugin 2011.4.0 does not build with gcc-4.7. There is an easy to fix
error about a missing include (already tracked and patched in
https://bugs.launchpad.net/hugin/+bug/913250) however there is another
issue that I have only seen on s390 yet:

Any ideas?

thanks, cu andreas
