Oh I see: Code that sets GNULIB_WARN_CFLAGS is already present in gzip/configure.ac (and likewise in coreutils, grep, tar) but not yet in diffutils/configure.ac. # We use a slightly smaller set of warning options for lib/. # Remove the following and save the result in GNULIB_WARN_CFLAGS. nw= ... gl_MANYWARN_COMPLEMENT([GNULIB_WARN_CFLAGS], [$WARN_CFLAGS], [$nw]) AC_SUBST([GNULIB_WARN_CFLAGS]) How about adding this block to the configure.ac of diffutils bison m4 sed that use the same idiom? Even if for the moment, nw remains empty here, the comment would make it clear that this is the mechanism to disable some warning options for lib/, and this would reduce the pressure on gnulib do placate style warnings like the two recent ones.
