Good news! Today's Austin Group meeting included a review of http://austingroupbugs.net/view.php?id=336, which is proposing that $(var$(V)) as a way of choosing between $(var0) and $(var1) based on the contents of $(V) be standardized in POSIX. If the 30-day interpretation window starting today does not raise any objections (that is, if no one complains of a counterexample existing make implementation that fails to meet the proposed wording), then automake's silent-make implementation will switch from exploiting unspecified behavior over to using a POSIX-standardized feature.
