it's hard to see how the code above could have been visible to the compiler
unless there is some other place it gets defined when found undefined.
Grepping the sources shows that in many cases #ifdef and #ifndef are used to
check this macro, but in other cases #if is used.  If we define it to 0,
obviously only the latter cases will work as expected.

Sorry ! I effectively used configure.com, but in the process of trying to
see
what was going on, I manually changed the variable.

Now, I restarted my build from scratch to get the minimal set of changes
which is working. I'll keep you informed.

But one of this change is the hardcoding of UCS-2LE in tds_iconv_open.
VMS only knows UCS-2. So iconv_open doesn't work, and because
initialization is not aborted, it keeps sending something the server
doesn't understand.

How did you solve that problem, Craig ?

ATM, I'm overwriting the strncpy.
