Hi,
I am using only LUA_USE_C89 macro that it should define
#define LUA_C89_NUMBERS 1.
next it should be
/* ** largest types available for C89 ('long' and 'double') */
#define LUA_INT_TYPE LUA_INT_LONG
#define LUA_FLOAT_TYPE LUA_FLOAT_DOUBLE
Compiler use defaults for FPU that it should be using inline FPU instruction for floating point.
