 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.
