More thought.

All these confusions come from the inability of commands to generate output
files separatedly.  This is perfect legal dependency tree because each
input/output relationship is 1:1

                 +-> arith.c --+
        arith.y -+             +-> arith.o
                 +-> arith.h --+

If yacc can generate only either .c / .h, like

        yacc --src arith.y
        yacc --hdr arith.y

We can write the rule straight.

What we need is to have wrapper commands which extracts one of outputs.  If
a command generates 3 outputs from 4 inputs, we need 3 wrappers.
