A good starting point is to comment out all the settings.

The `make' program will set most of the correctly by default.
See the make info page.

A good initial setting for CFLAGS is

  CFLAGS=-g

which enables debugging support.

For the final pre-installation compile, set it to:

  CFLAGS=-O2 -s

which does reasonable optimisation and strips unnecessary
clutter from the executable.

The resulting compile command line printed by make should
look like:

cc -c -O2 -s fred.c

and the link command line will look like:

cc -O2 -s -o fredsystem fred1.o fred2.o fred3.o
