Version 1.7 - edward
Aug 3, 1994
--------------------
- Fixed a bug in what_search_type() that set target_arg_first = 0 when
the srchtype was I_SOURCE_SRCH.  The target argument should be before
the nodeid so I set target_arg_first = 1.

- Expanded on the #define MIT, #define UPENN, and #define TEST.
Instead of them doing three separate things TEST now works in
conjunction with UPENN and MIT to set things as appropriate for UPenn,
UPenn's test server, MIT, and MIT's test server.

- Added the variables test and CC to the Makefile.  Set test=-DTEST
for the test server.  Set CC to cc or gcc.  The Dec's cc can't handle
ANSI style string concatentation.  See send_search_form().

- Fixed a bug in main().  The first printf (if access_denied) started
out
    printf ("\<Title>TechInfo Gateway Unavailable</title>\n\

The '\' before the '<' is unnecessary.

- Modified get_send_doc() to pass error messages from the server back
to the user so the user doesn't get a message saying the document
can't be accessed.  This is need for the MIT Eyes Only feature that
returns the error "This file cannot be accessed outside of MIT."

- Modified whatis_titype() and whatis_type() to handle the restricted
access bit (N_PRIVATE_IP).  whatis_type() puts the extension .html onto the end
of the URL for restricted nodes and whatis_titype() identifies any
restricted item as being NT_ASCII because that's what the message from
the server will be.  See the two procedures for more details.
