SYSTEM DEPENDENCIES
System-system differences for TCP include files and macros. This
file includes for each system the files necessary for network and
file I/O. It should be used in conjunction with HTUtils.h to help
ensure portability across as many platforms and flavors of platforms
as possible.

VAX/VMS
Under VMS, there are many versions of TCP-IP. Define one if you do
not use Digital's UCX product:
UCX DEC's "Ultrix connection" (default)
CMU_TCP Available via FTP from sacusr.mp.usbr.gov
SOCKETSHR Eckhart Meyer's interface to NETLIB
WIN_TCP From Wollongong, now GEC software.
MULTINET From SRI, became TGV, then Cisco.
DECNET Cern's TCP socket emulation over DECnet
The last three do not interfere with the
unix i/o library, and so they need special calls to read, write and
close sockets. In these cases the socket number is a VMS channel
number, so we make the @@@ HORRIBLE @@@ assumption that a channel
number will be greater than 10 but a unix file descriptor less than
10. It works.
