Bug#525750: FTBFS with GCC 4.4: dereferencing type-punned pointer will break...

[Martin Michlmayr]

Package: libphysfs
Version: 2.0.0-2
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-4.4
Tags: patch

Your package fails to build with GCC 4.4, which has 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 or
gcc-4.4 from experimental.
