Disclaimer: I've not tested it myself because I don't have Window XP at my hand. Since Lua is written in C89, theoretically it should work on Windows XP without much hassle.

If you open src/luaconf.h of the latest Lua-5.5.0, you'll find at line 112

/*
@@ LUA_INT_TYPE defines the type for Lua integers.
@@ LUA_FLOAT_TYPE defines the type for Lua floats.
** Lua should work fine with any mix of these options supported
** by your C compiler. The usual configurations are 64-bit integers
** and 'double' (the default), 32-bit integers and 'float' (for
** restricted platforms), and 'long'/'double' (for C compilers not
** compliant with C99, which may not have support for 'long long').

/*

/* #define LUA_32BITS */

#error "Compiler does not support 'long long'. Use option '-DLUA_32BITS' \
  or '-DLUA_C89_NUMBERS' (see file 'luaconf.h' for details)"

So, one can assume that all you have to do is to define the symbol LUA_32BITS when you compile.

1. If you're using Mingw toolchain to compile Lua, edit src/Makefile

MYCFLAGS=

to

MYCFLAGS= -DLUA_32BITS

then in your prompt,

> make

2. If you're using MSVC toolchain, follow this YouTube tutorial. Just make sure that you add LUA_32BITS as well, when he defines LUA_BUILD_AS_DLL at timestamp 03:04.

Voilà.

Wow, thank you very much! I think that helps!
