Description
一开始其他平台编译luajit报错lua_tointegerx 的static定义有问题，注释掉这段之后继续
#if LUA_VERSION_NUM < 502
/* static int64_t lua_tointegerx(lua_State *L, int idx, int *isnum) {
if (lua_isnumber(L, idx)) {
if (isnum) *isnum = 1;
return (int64_t)lua_tointeger(L, idx);
}
else {
if (isnum) *isnum = 0;
return 0;
}
} */
到后面又有报错，提示lua_tointegerx定义不清晰，看了下，macos下编译luajit，用的是lua5.1的代码，就会有问题
/Users/runner/work/xLua/xLua/build/sproto/lsproto.c:295:8: error: implicit declaration of function 'lua_tointegerx' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
想问下这里应该如何兼容各种情况呢？

Research direction
Start with build/sproto/lsproto.c and inspect how lua_tointegerx is declared or used under Lua 5.1 and LuaJIT. Reproduce the macOS compilation error and compare it with the other platform builds; done means the relevant configurations compile without the implicit-declaration or conflicting-definition errors.
