i am happy to report that LibreDWG succesfully builds the tarball on
Hydra, and makes a good show of building the "make check" prerequisites
for several platforms on Hydra.  Now, a good show is not success and
even less so "make check" success, so it is not yet time to celebrate.

This message is intended, instead, to invite the rest of the LibreDWG
hackers to fix up the warnings and errors (and segfaults!) unearthed by
these builds.  To start, have a look at:

 http://hydra.nixos.org/jobset/gnu/libredwg-master

Then, follow the links (eventually) to a "raw" link, such as:

 http://hydra.nixos.org/build/17704711/nixlog/1/raw

Lastly, search the contents of that page for "error" or "warning" or
"segmentation fault", find something you can fix, and fix it, locally.

But why locally?  Why not just push the fix?

Well, i am going to be blunt here: I'm not happy w/ the quality of some
of the more recent commit messages.  They do not conform to the GNU
coding standards.  IMHO, it's too much of a pain to change them now,
but we should make a strong effort to improve ourselves going forward.

So, i propose to serve as a mentor for this very narrow aspect of
LibreDWG hacking (commit message construction), and explicitly not for
any other aspect (design, implementation).  The work flow is like this:

 (a) jrhacker finds PROBLEM (see above)
 (b) jrhacker signals mailing list: "i'm on it; PROBLEM is mine!"
 (c) jrhacker fixes PROBLEM and commits to local repo
 (d) jrhacker posts patch series (see git-format-patch(1))
 (e) ttn critiques the commit message(s)
 (f) jrhacker rolls eyes, refines the series, reposts
 (g) goto (e) unless ttn finally shuts up
 (h) jrhacker pushes to the savannah repo

BTW, if there are design / implementation critique from non-ttn
hackers as part of (e), then that's fine, too.  This way, we get
(technically) the fixes and proper commit messages, and (socially)
a chance to get to know each other better.  All in the name of GNU,
of course!

What do people think?
