--- Comment #2 from SASANO Takayoshi <uaa at mx5 dot nisiq.net> --- Hello, can you tell me more details to do? I think "some better way" seems to be one of them as follows. 1) change "#if __INT_WIDTH__ > 16 ~ #else ~ #endif" to "#if defined(__INT_WIDTH__) && (__INT_WIDTH__ <= 16) ~ #else ~ #endif" to safer choice. 2) remove "#define DMGL_OPT_BIT(x)", all "#define DMGL_..." uses (1 << x). 3) abandon remap bit position for int=16bit architecture, modify codes that can pass 32bit-value option. 4) others (I have no idea...) please tell me.
