In my build system I have $(call message) function that accepts
two arguments: first is what to print, second is what to execute:

%.o : %.cxx
        $(call message,c++ $<,g++ -c $< -o $@)

But that's not all. There is also a variable called `verbose' which,
when defined, makes `message' print what it's actually executing. Very
handy when debugging.
