Bug#575610: Wrong types on 64-bit systems

[Kuratius]

I believe the issues you're seeing are due to wrong types and format
specifiers on 64-bit systems. They disappear if you compile to a 32-bit
executable or if you use the proper types from stdint.h.
This game is from 2002, it is likely expecting long to be a 32-bit type and
not a 64-bit type and hence has buffer sizes for sprintf that correspond to
that. At least for me locally, after getting past dozens of compiler
warnings, changing the code to use int32_t where appropriate fixes these
bugs.
