netinet/in.h defines "ntohl", and the application I referred to also
has a "default" definition for "ntohl" and other networking functions
that happens when it can't correctly determine the "unix" environment
in which you are compiling.  In my case, the application is not really
fully DJGPP-aware yet, so the application headers do the "wrong thing"
for DJGPP compilation.

Thank you, Richard!  That was a most helpful exposition.  It was
exactly what I was requesting.  I commend you for your honesty and
clarity.
