Dear Sir,

I'm glad to hear your comment and thank you for spending
your time about this issue. I have to reply another post
from you but it requires more consideration.

Excuse me, unmodified ft2build.h just defines like this.

        #ifndef __FT2_BUILD_GENERIC_H__
        #define __FT2_BUILD_GENERIC_H__

        #include <freetype/config/ftheader.h>

        #endif /* __FT2_BUILD_GENERIC_H__ */

Do you propose to insert some conditionals into here? Like...

        #ifndef __FT2_BUILD_GENERIC_H__
        #define __FT2_BUILD_GENERIC_H__

        #if ...   /* Conditional_for_arch_1 */
        #include <freetype/config/arch_1/ftheader.h>
        #elif ... /* Conditional_for_arch_2 */
        #include <freetype/config/arch_1/ftheader.h>
        #elif ...

        #endif /* __FT2_BUILD_GENERIC_H__ */
