[Pkg-scicomp-devel] Bug#527210: FTBFS with GCC 4.4: missing #include

[Martin Michlmayr]

Package: trilinos
Version: 9.0.2.dfsg-1
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-4.4/g++-4.4 from unstable.
