[Greg Chicares]

branch: master
commit afed971f4496cfb091d9fa5dd924de932e152f7e
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Remove support for cygwin-native build [391]
    
    Removed outmoded workarounds for an ancient version of newlib, and
    directives that would have included a makefile that was expunged before
    the lmi epoch.
