Hi Silien !

Yann m'a dit qu'il y avait une branche
"stable" qui me permettait
d'éviter les erreurs de compilation avec les Warnings.
I though that in the past I had arranged things so that -Werror would
only be used for development versions, but it seems I was wrong.
-Werror was always used.
cc1plus: warnings being treated as errors
tgbasafracomplement.cc:57: warning: ‘spot::safra_tree_automaton’ has a
field ‘spot::safra_tree_automaton::automaton’ whose type uses the
anonymous namespace
This warning is actually a bug in g++-4.2. See
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29365. Later versions of
GCC should not warn about this construction.
Even so, I have changed Spot's code
1) so that it should not trigger this warning any more (I could not
test this, because version of g++-4.2 seems to be patched not to warn
about this)
2) so that future stable releases of Spot will not use -Werror by default
3) so you can explicitly disable all extra warnings and -Werror
flags with `./configure --disable-devel`.
You can configure your build tool to use "git clone
git://git.lrde.epita.fr/spot" in order to compile the new code. This
is not a released version, so -Werror will be on by default, but
tgbasafracomplement.cc should not produce a warning anymore, and you
can also add --disable-devel if you encounter more warnings (but
please do report them to me, any warning is worth fixing).
