If you're lazy, just type "make" and see if compiles.  Otherwise read
and edit config.h, then the Makefile.

The two biggest problems I could imagine would be (1) the variable-arguments
part (you MUST have one of <stdarg.h> or <varargs.h>), and (2) Getting the
code to link with your RPC libraries.  config.h lets you choose for (1),
but for (2) you MUST have the rpcsvc library, and you MAY need an additional
library or two that the rpcsvc library requires to link.  For my system I
need both the "rpcsvc" library and the "sun" library.  The program can
live without RPC, but it is MUCH more efficient net-friendly, so I
highly recommend it.  config.h will let you try compiling without it,
though.
