Error when building luarpc

[JohnTordur]

When trying to build luarpc, the build errors.

src/modules/bit.c:43:8: error: ‘s64’ undeclared (first use in this function)
   43 |   ( ( (s64)luaL_checknumber((L), (n))) & 0x0ffffffff  )

I tried to declare it like this in bit.c

/* Quickfix */
typedef signed long long s64;

This builds the projet, but I'm unsure if it is the proper solution?

This is a bit delicate. The code was meant to be built in 32 bit mode and I just noticed that the required compilation flag is missing in rpc-lua.lua. I fixed that in the last commit, but it makes it incompatible with Apple silicon builds, since they don't support 32 bit mode. I'd try Linux on an Intel machine if possible.
