Reminder : do NOT hardcode deprecation flags in tarball

[Frederic Crozat <fcrozat mandriva com>]

Hi everyone,

just a quick reminder about deprecation flags and tarball release :
please avoid at all cost to hardcode deprecation flags in compilation 
flags, when a module is built from a tarball (it is ok to have such 
flags when building from gi checkout).

Why, you may ask ?

Well, I'm currently strugling with smoketesting GNOME 2.29.5 release and 
there are some tarballs no longer building because new G_SEAL 
deprecation were added in yesterday GTK+ 2.19.3 release and some modules 
were not fixed for this.

Current guilty modules :
- vte (bedhad is cooking a new release)
- gnome-utils

In a similar idea, try to avoid releasing tarballs which depends on 
other unreleased tarball module version.

Thanks you for your attention.
