[Diffutils-devel] FYI: two diffs pushed to pass "make distcheck" with GCC 7

[Jim Meyering]

GCC-7-to-be added some new warning options, so I've fixed both
diffutils and the bits of gnulib it uses so that "make distcheck"
still passes when using that compiler:

    gnulib: update to latest

    build: avoid GCC 7's new warnings
    * src/util.c (get_funky_string): Adjust comment so that GCC 7's
    -Wimplicit-fallthrough recognizes it.
    * src/diff3.c (main): Cast boolean MERGE to "int" to avoid this:
    diff3.c:341:25: error: '~' on a boolean expression \
    [-Werror=bool-operation]
