Bug#454852: FTBFS with GCC 4.3: missing #includes

[Martin Michlmayr]

Package: etl-dev
Usertags: ftbfs-gcc-4.3

Your package causes other packages to fail 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.
