I am pretty sure that all of the final Max 3.x builds were done under OS/2,
so your mileage with Win XP may vary.

The "_" prefix comes from the standard convention used by WATCOM
C: variables with external scope automatically have a "_" prefix
added. In other words, don't worry about it.

I don't recall exactly which version of the source is out there, but the
last one I have at my disposal has Rxframeind and Rxtype both defined and
used in prot/zm.c. I don't know if I still even have my WC discs lying
around anymore, so I am not at liberty to try compilation...but if I had to
hazard a guess, I'd say that there appear to be conflicting declarations
for those two variables.

In ZM.H,the declaration is "extern Rxframeind", whereas it is
"static int Rxframeind" in ZM.C. "extern" implies the
opposite of "static", so maybe if you delete the lines containing
the extern references for those variables in zmodem.h and zsjd.h, the
compiler may be happy.

Just keep in mind that I haven't looked at this code in a very long time,
so take that advice for what it's worth!
