We had a short chat with Nathaniel yesterday on IRC about which C standards
we, as a project, allow. I think this patch is a result of that discussion.

SSSD has had -std=gnu99 in the default CFLAGS for more than a year now.

I think we can safely support C99 and its features now, it's almost 2014
and all major compilers support the features we care about. But I think
this change should go hand-in-hand with amending

For instance, would variable-length arrays considered OK? (I would vote
yes), would intermingled code and declarations be considered OK (I
personally dislike these), etc?
