   Log Message:
   ${GENCMD} is used to generate only one output from file generation commands
   which potentially have multiple output files, which confuses make(1).
   
   This wrapper copies all involved files into /tmp, execute the command, and
   copy the wanted file back to ${.OBJDIR}.  If this is expensive, consider to
   rewrite the generation command to output files individually.


this seems pretty gross.  i'm not sure it's a good way to
solve the problem at hand.  it hides everything away with
@.  it also doesn't appear to avoid updating a file if it
hasn't actually changed.  it also hard codes /tmp, which
it shouldn't need to use at all.  it also uses "cp"
instead of "mv".

did anyone review this?
