[lmi-commits] [lmi] master f8a78ba 15/30: Add a CI build using clang with autotools too

[Greg Chicares]

branch: master
commit f8a78baf03860a8cacc1bf9cb006c4a764cf017f
Author: Vadim Zeitlin <vadim@tt-solutions.com>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Add a CI build using clang with autotools too
    
    Note that the build also uses libc++, rather than libstdc++ that clang
    under Linux uses by default, to test not only another compiler, but also
    another standard library implementation.
    
    And also because compiling unwind.cpp with clang/libstdc++ doesn't work
    currently (while when using libc++ this file is not compiled at all).
