-## `MRB_USE_FLOAT32`

-Changed from `MRB_USE_FLOAT` to make sure `float` here means
-using single precision float, and not the opposite of

-## `MRB_USE_METHOD_T_STRUCT`

-Changed from `MRB_METHOD_T_STRUCT`.

-To use `struct` version of `mrb_method_t`. More portable but consumes more memory.
-Turned on by default on 32bit platforms.
