Note that we already require 1.11 or higher for parallel-tests.
I wouldn't mind if we also just added AM_SILENT_RULES([yes]) by default.

I like this patch. Just one question, what defines the $(AM_V_foo)
(specifically AM_V_CC and AM_V_CCLD) variables? I only see AM_V_at and
AM_V_GEN described in the automake manual. Are they officially OK to
use? OK to push if they are. Otherwise I think we should define them (or
some renamed version ourselves based on the official AM_V_GEN macro).

Thanks,

Mark
