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!
