## This unpleasant duplication of rules makes the build system basically work
## for non-GNU make(1) variants, while GNU Make will associate useful
## additional dependencies with the test programs.  GNU Make seems not to
## mind the duplicate rules, and uses the second (better) set; non-GNU Make
## will think the second set refer to bizarrely-named targets which nobody is
## apparently interested in.
