[lmi-commits] [lmi] master 6b3860f 2/5: Disable MSVC warnings in bourn_cast.hpp

[Greg Chicares]

branch: master
commit 6b3860faf0dc9b70ee649e31ee4f69ca384340be
Author: Vadim Zeitlin <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Disable MSVC warnings in bourn_cast.hpp
    
    Use compiler-specific pragmas to avoid unavoidable (or, at least,
    difficult to avoid), but known to be harmless here, warnings about
    signed/unsigned and boolean comparisons with MSVC, just as we already
    do it for gcc/clang.
