After discussions on tech-toolchain (1), I've modified the patch
regarding Issue 7 (.NULL special target). I had missed one aspect,
which has no substitute. .NULL target is still available, but it is
now documented and does not break single suffix rules.
The earlier version of the patch also made $(.IMPSRC) unavailable
for explicit rules like it was said in the manual page it should be.
It was available as a side effect of issue 8 (suffix rule dependencies
forced on all targets). Based on another discussion on tech-toolchain (2)
I made $(.IMPSRC) available in explicit rules like it is available
in gmake (the first prerequisite).
The patch is available in the same location as before.
