42 # command that was intended to be run when it's not available as "make".
43 # For GNU make this is typically "gmake" and for BSD make typically "bsdmake".
44 # For kmk this should be "kmk".

49 # and $(MAKE__COMMAND__NAME) will pick them up from there.
51 # In case any of the other targets are not recognized as special, the default
52 # target must be the first target and it depends on a file that should not exist
53 # just in case .PHONY is not supported by the "make" that's reading this file.
54 # This rule will be used if no targets are specified on the command line. We
55 # must not name it "all" because we do not pass the target name on in this case
56 # -- that is handled by the .DEFAULT rule.
