Package: log4cxx
Version: 0.9.7-6
Usertags: ftbfs-gcc-4.3

Your package fails to build with GCC 4.3.  Version 4.3 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning.  In GCC 4.3, the C++ header
dependencies have been cleaned up.  The advantage of this is that
programs will compile faster.  The downside is that you actually
need to directly #include everything you use (but you really should
do this anyway, otherwise your program won't work with any compiler
other than GCC).  There's some more information about this at
http://www.cyrius.com/journal/2007/05/10#gcc-4.3-include

You can reproduce this problem with gcc-snapshot from unstable.  Note
that Red Hat, Novell and Ubuntu have done some work getting packages
to build with GCC 4.3 so there might be patches floating around
somewhere.  I suggest you talk to your upstream.
