Package: octave3.0
Version: 1:3.0.1-6lenny1
User: debian-gcc@lists.debian.org
Usertags: ftbfs-gcc-4.4

Your package fails to build with the upcoming GCC 4.4.  Version 4.4
has not been released yet but I'm building with a snapshot in order
to find errors and give people an advance warning.

GCC 4.4 cleaned up some more C++ headers.  You always have to #include
headers directly and cannot rely for things to be included indirectly.

You can reproduce this problem with gcc-snapshot from unstable.

Unfortunately I'm not sure if this patch is complete because my build
fails with:

I'm not sure what this is about.
