Hello, Currently sysdef.h includes C headers for little purpose, as the same headers are already pulled in appropriate .c files. In the result the headers listed in sysdef.h are pulled in twice.
I propose to move the remaining content (literally 11 lines-of-code) to def.h or a better place. I think that back in time all system includes were pulled in from sysdef.h, today I see no need for it any more.
