[lmi-commits] [lmi] master 6143242 06/10: Use a pragma to inhibit certain warnings in a single TU

[Greg Chicares]

branch: master
commit 61432429678d38824fafcceafaf881fc862da469
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Use a pragma to inhibit certain warnings in a single TU
    
    Either way has its advantages. This change is just one step toward a
    different style preference, which may someday seem regrettable.
