Bug#504950: FTBFS with GCC 4.4: missing #include

[Martin Michlmayr]

Package: opencity
Version: 0.0.5.1stable-1
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-4.4
Tags: patch

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.
