By "pattern matching default rules" you mean gmake rules of the form
"%.o: %.c"?

As for suffix rules, a few years ago we had someone come through and
dump "POSIX compliance" patches for suffix rules that both crippled
the feature and broke the world, and the conclusion after that was
that since POSIX apparently demands that the feature be crippled we
were going to ignore it and move on.
