[Vala] Binding issues

[Giulio Paci <giuliopaci interfree it>]

Hi to all!
    Today I was experimenting with libarchive bindings and I found that 
archive_read_support_format_raw() was not available in the current binding.

Adding the line
public Result support_format_raw ();
just after the line
public Result support_format_zip ();
fixed the problem for me.

What is the best way to report problems like this?
I have reported a similar issue with the bug tracking system 
(https://bugzilla.gnome.org/show_bug.cgi?id=639883) in the past, but it 
seems that it has been ignored.

Bests,
    Giulio.
