Re: [Vala] Vala support for automake

[Ralf Wildenhues <Ralf Wildenhues gmx de>]

Of course my testing went a bit overboard before merging, so I actually
missed a couple of vala-related failures.  Fixed with this patch, pushed
to master.  (next has been merged into master.)

Cheers,
Ralf

    Fix AM_PROG_VALAC version requirement detection.
    
    * m4/vala.m4 (AM_PROG_VALAC): Remove `Vala ' from valac
    --version string before comparing versions.
    * tests/vala2.test: Require version 0.7.0 for the test.
    Fixes failures of vala2.test and vala3.test with older valac.
