Good news!  Today's Austin Group meeting included a review of, 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.
