 I disagree.  It's exactly a matter of what the rules mean.  From your
 description, you seem to think that "target1 target2: source" means that
 this is a single rule that builds 2 targets.
 talks a lot about the syntax of the dependency declarations but misses
 to mention explicitly that each target is handled separately, there are
 no groups of targets.  The manual page for make(1) is as silent as POSIX
 in this regard.
 NetBSD make and GNU make agree on how to interpret the dependency
 "target1 target2: source" though.  They both treat the targets as
 independent.  Therefore I don't see any need to change the code.  It
 would be good to mention this independence in the documentation and ask
 POSIX to add it to the specification for their next issue.

 If we assume that a1 and a2 are independent (as GNU make and NetBSD make
 treat them), why would make be required to check that both files have
 been updated?
