I wonder how to interpret your message.  Are you asking for advice? 
Letting others know?  Expecting a fix?  

As the project maintainer, what I would like to see is a message saying,
"I couldn't compile [version] in my environment on [system] with
[compiler].  Please see attached patch that makes it work for me."  

We try -- we really do try -- to make the FreeTDS code as portable as
possible.  It's a collaborative effort.  I build in Win32 from time to
time, and the code compiles for me in my environment.  Others do, too.  If
it doesn't build in your environment, it's because something's different. 
No one but you has access to your system and can determine what, exactly,
is wrong.  That's why a patch would be so much better than a a game of
three-code monte.

LONG_MIN is defined, it seems, in Microsoft's limits.h.  src/tds/config.c
says:

        #if HAVE_LIMITS_H
        #include <limits.h>
        #endif 

but win32/config.h doesn't define it:  

        $ grep -ci limit win32/config.h 
        0

So, the real mystery is why it works at all!  But it's quite possible some
other file, perhaps a system header file, does include limits.h in some
versions of Visual Studio.  Or maybe "VC6" (I don't remember which one
that is) didn't have a limits.h at all, doesn't define LONG_MIN?  What
does your documentation say?  

If you do have it, then I would try adding 

        #define HAVE_LIMITS_H 1

to win32/config.h.  

HTH.  I look forward to your patch!  :-)
