please fix build failures, including those introduced by GCC 5

[Matthias Klose]

Hi,

two test rebuilds for vivid are almost finished on all architectures (pending
powerpc and arm64).  It's time to address the build failures seen with these
test rebuilds.  The most important ones are listed in [1] for the vivid
archives.  These really have to be addressed.

In preparation for the w-series (15.10), there was another test rebuild using
GCC 5 (yes, GCC 5 will be the default for 15.10, without any possibility to fall
back to older g++ and gfortran versions).  Some outfall as usual [2].  I think
the switch to GCC 5 will cause a bit more work than the switch to GCC 4.9 in
utopic, so I would like to address as many issues as possible before the switch,
even during the preparation of the 15.04 (vivid) release.  Safe uploads to vivid
would be appreciated.  To check for buildability with GCC 5, add the
ubuntu-toolchain-r/test PPA [3] to your apt sources.  If you have time to kill,
please fix these issues now.  Make sure to forward fixes to the Debian bug
tracker, bugs were filed for a Debian test rebuild as well [4].  Help for
porting issues can be found in the GCC 5 porting notes [5] and an analysis of a
test rebuild for another distro [6].

If you can't, or if you don't want to do an upload, please make sure to file a
launchpad issue, and tag it with 'ftbfs' and probably 'patch', then the issue
will show up in [1] and [2].

Help would be appreciated to fix issues in packages like boost so that we can
get more reliable test rebuild results.

Thanks, Matthias
