How is that relavant to this bug?  The whole point of Paul's proposal is
that @AM_V@ and @AM_DEFAULT_VERBOSITY@ are automake internals, and
appear only in Makefile.in, not Makefile.am.

You're asking for something different, which is a smarter automake that
can handle Makefile.am in such a way that it can see through a
user-provided @MODULE@, even when it is later spelled $(MODULE).  But
that is unrelated to fixing AM_SILENT_RULES to produce POSIX-compliant
makefiles.
