Here's the deal: At least two patch sets have been posted to Automake mailing lists during the last year in order to improve Vala support in Automake. We cannot take either because the authors couldn't complete copyright assignments for reasons not further relevant to this message.
So here's a call for help: if there is something broken with Vala support in Automake, you can contribute by writing bug reports rather than by sending patches. Describe in your own words how things are supposed to work, or show your projects; given precise enough semantics, it is fairly straight-forward to fix the implementation. But we cannot do anything with nontrivial patches that are not assigned to the FSF, and in order to stay clean of potential problems I don't look at the patch posts at all. So *please* don't post them unless you're also willing to go all the way. Thanks, Ralf
