There is a build rule that is causing a problem because it says that if

myfile.a myfile.b myfile.c: myfile.source
process $<
process then opens all 3 output files for writing.

The ideal solution is for make to link all 3 output files together, so
that as soon as it fires the job to process any of the 3, all 3 are
marked as “running” and no further jobs are started. Is this possible
with make?
I recently wrote an article for CM Crossroads about precisely this topic:
