[lmi-commits] [lmi] master 55cc6938 01/24: Establish an initial blacklist of clang warnings

[Greg Chicares]

branch: master
commit 55cc6938f15d73b24a2ace7cdc5dcc8bb53ee6d9
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Establish an initial blacklist of clang warnings
    
    With gcc, '-Q --help=warning' shows warnings that are not enabled, and
    one whitelists them piecemeal. With clang, there's no such option, so
    one enables all warnings and blacklists them piecemeal. This initial
    blacklist includes every warning that clang would issue for lmi. It is
    anticipated that some will be removed after changing the code.
