You have four options, changing:

        int gold;
        int exp;


A) 'unsigned int', and the audit every bit of code that uses gold and
experience to make sure they use unsigned integers as well and don't let it
go negative. Then you get 0 to 4,294,967,296.

B) 'long', and buy a 64-bit platform like Alpha, Itanium, or Sparc64.
9,223,372,036,854,775,808 should be enough for you.

C) 'long long', and take a speed hit and hope the compiler doesn't have any
errors compiling the code.  Same range as B), just a lot slower.

D) just holding smaller numbers, requiring a change to all your mobiles and
existing players.  4 billion experience? Phew.

The decimal constant warning can be eliminated by tagging your numbers as
"1000UL" (for 'U'nsigned 'L'ong).
