Comment(by glynn):

 Replying to [comment:6 hamish]:
 > ok, so the question becomes what uses Python.make,

 Python.make is used by gui/wxpython, gui/scripts, scripts/r.in.wms, and
 various subdirectories of lib/python.

 GRASS 7 doesn't have any C or C++ code which links against the Python
 library. The preferred way of integrating C and Python code is to use
 ctypes to access C functions from Python.

 The PYTHON make variable exists to simplify the case where the default
 "python" command isn't suitable for GRASS (e.g. because it's Python 3.x,
 or it doesn't have the numpy, wxPython, etc packages). In such cases, it
 can be overridden on the command line, e.g. "make
 PYTHON=/usr/local/bin/python2".
