| Title | MPS does not compile with Clang 6.0.0 |

| Description | On Ubuntu 18.04: $ clang --version clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final) $ make -f lii6ll.gmk testrun error: unknown warning option '-Wno-extended-offsetof'; did you mean '-Wno-invalid-offsetof'? [-Werror,-Wunknown-warning-option] |
| Analysis | The -Wno-extended-offsetof flag was provided to avoid failed compilations from clang -pedantic due to the use of "extended" (non-standards-conforming) calls to offsetof (see job003619). But these calls were all removed in [1], so the flag is no longer needed. |
