[lmi-commits] [lmi] master 67455db4 06/11: Expunge obsolete history

[Greg Chicares]

branch: master
commit 67455db4a43e7c4672d152f7e30391f0ca748e5b
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Expunge obsolete history
    
    The reasons for using various options with old gcc versions are usually
    of little interest today:
     - libstdc++ engendered some warnings
     - a bad snprintf() was replaced by a better one
     - "hello world" failed to compile
    
    The discussion of '-fomit-frame-pointer' remains relevant; therefore,
    retained it, and expunged only duplicative citations.
