You would be better off with the Max/MSP extern documentation as it is
much closer to PD than jMax. There is close to a direct mapping between
Max externals and PD externals for the most basic operations. Also, take
a look at the PD source itself - many of the objects are fairly simple and
easy to read.

Is there some reason not to use the makefiles? I know make can be
annoying at times but it would probably be easier in the long run.

Again, the source is a great help. For the guts of netsend/netreceive
you need to look at both x_net.c and s_inter.c (for sys_addpollfn).
