Neither would I; claiming that strict POSIX-compliance is the end-all goal
makes no sense imo.

My proposal for adding $^ as an alias for $> does not add any
incompatibilities, neither with POSIX nor with any existing BSD make. Only
Terry has said that BSD make used to use $^ but so far he hasn't shown any
proof that this is still in use anywhere.

Writing Makefiles is a pain, period.

Needless to say, I'm certainly not advocating that we do this.
