Bug#623634: libnet-rawip-perl: miscalculates header checksums

On my search in the web, if there was already some solution for 'my'
libnet-rawip-perl problem, I found two patches; these are attached. The
patch Net-RawIP-0.23-format.patch (from Redhat/Fedora) removes that format
problem; the patch nonreturn-in-nonvoid.patch (from OpenSuse) adds a
missing default:-part in a switch-statement.

Additionally, I attached a patch cc.patch for setting gcc-4.6 as compiler.
Of course, gcc-4.6 must be added to Build-Depends.

libnet-rawip-perl_0.25-1+b2_amd64.deb works for me on a wheezy system. It
also works on a jessie system after downgrading some other packages.
libnet-rawip-perl_0.25-2_amd64.deb fails on a jessie system. Version
0.25-1+b2, rebuilt from package sources on a jessie system, also fails
there. But version 0.25-2, rebuilt from sources after adding the attached
patches and a Build-Depend on gcc-4.6, works.

Regards
