The programming guide doesn't match reality in all cases.  The thing
that you need to know to get programs to link is there is only one
library called TWGLIB.  It replaces LIBNET and LIBNETACC.  These
libraries are for use only by Euncie.  There should have been stuff in
the release notes about this, but my memory here is a bit faded.

No.  size_t gets redefined from an unsigned int to a signed int (since
VAX-C has int == long).  Unless you are dealing with very large
objects, this shouldn't be a problem.  The original definition is in
something like SYS$LIBRARY:TYPES.H or some other include VAX-C include
file.  If you remove it from [NETDIST.INCLUDE.SYS]TYPES.H, then the
error will go away.  You can also change it to "typedef unsigned int
size_t".

Also, you should be using the types.h file from
twg$tcp:[netdist.include.sys] off the 5.1 tape.  It is not in the VMS
4.x installation saveset due to an oversite.  You can get it out of
the "B" saveset (fullname WIN_TCP051.B I think).

This section is wrong.  The libraries that you use have changed in
release 5.1.  You should add the following to your login.com

$ define LNK$LIBRARY SYS$LIBRARY:VAXCRTL.OLB
$ define LNK$LIBRARY TWG$TCP:[NETDIST.LIB]TWGLIB.OLB

>%LINK-W-NUDFSYMS, 2 undefined symbols:

These routines are found in LIBNET, so if you list that after the
LIBNETACC (for a second time), you shouldn't get errors.  However, you
will be better off in the long run by using TWGLIB.

Try these suggestions.  They should help.  All of the above is from
memory, since I no longer work for TWG.
