# newer makes predefine $(MAKE) to 'make' and do smarter processing of
# recursive make calls if $(MAKE) is used
# these makes allow $(MAKE) to be overridden by the environment if someone
# wants to (or has to) use something other than the standard make, so we do
# not want to unconditionally set $(MAKE) here
#
# unfortunately, some older makes do not predefine $(MAKE); if you have one of
# these, uncomment the following line
# (you will know that you have one if you get complaints about unable to
# execute things like 'data' and 'rumors')
