The object code produced from the contents of this directory are required
by various parts of MAPUX (mostly the utilities) and are linked with when
you make the programs.
To produce the object files themselves simply use your favourite C 
compiler and assembler to produce .o versions.  I used hcc (note that
lmath is required by the hcc compiler only and can be discarded if you
have a different compiler) and A68K and PhxAss.
