## This test target should really depend on a timestamp to only perform
## work when makeutils.mk is modified.  That answer would require using a
## 2nd makefile imposing more shell overhead.  Separate makefiles would be
## very handy for testing when pwd==$src/ but for now avoid the overhead.
##
## Test logic will be interpreted at compile time, 'fast' and 'required' so
## the test will always be run when testing is enabled.
