Bug#417897: Causes FTBFS with GCC 4.3: missing #includes

Package: etl
Version: 0.04.08-2
Usertags: ftbfs-gcc-4.3
Tags: patch

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).  Some background of this can be found at

You can reproduce this problem with gcc-snapshot (20070326-1 or higher)
from unstable. (Currently not available for i386, but for amd64, powerpc
and ia64.  I hope to have i386 binaries in the archive in ~3 weeks.)
