I see that the configure.ac of diffutils 3.2 (currently in Buildroot) has AM_PROG_CC_STDC, it has been removed since then. If diffutils uses C99 constructs, then it should be specifying AC_PROG_CC_C99 in its configure.ac, I guess. Of course, what you propose is a relatively simple workaround, but I believe the real fix is in diffutils itself. Best regards, Thomas

Hi Thomas, Thanks for the review and please ignore this patch. I have no idea why I cannot reproduce this issue now. I can build diffutils without this patch today. Regards, Axel
