 Title: #377: This patch set fixes a bunch RHEL6 warnings
Action: opened

PR body:
"""
Those patches were part of PR#50, which got stuck for a long time and ended up closed as
it didn't seem interesting for the project.

However, after some time another PR (PR#371) fixes the very same issues. So, I'd like
to have my patches (at least) considered and, if possible, reviewed.

In any case, this PR is basically PR#50 without the patch that makes use of gnulib many
warnings.
