[Pkg-kde-extras] Bug#455633: FTBFS with GCC 4.3: missing #includes

Package: exiv2
Version: 0.15-1
Usertags: ftbfs-gcc-4.3

Your package fails to build with GCC 4.3 and it breaks other packages
(e.g. ufraw).  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.
