I'd like to be able to specify the actual location of the sources on make's command line. Doing it with make .PATH=/path/to/sources does not work. But make VPATH=/path/to/sources works. The manual page labels VPATH as deprecated -- advising use of .PATH instead. Clearly, .PATH is not a complete replacement. However, .PATH is also frowned upon by the manual page... I suppose, I can always add a line like: .PATH: ${THEPATH} then invoke make with THEPATH=/path/to/sources -- but why is this any better?
