[lmi-commits] [lmi] master 2cd4fe1 4/6: Only compile unwind.cpp when using libstdc++

[Greg Chicares]

branch: master
commit 2cd4fe19a621eba209720d453bcc4c9395840673
Author: Vadim Zeitlin <vadim@tt-solutions.com>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Only compile unwind.cpp when using libstdc++
    
    The code in this file uses libstdc++-specific types such as
    __class_type_info and __dynamic_cast that are not provided by the other
    compiler/standard library implementations, such as clang, so building it
    with them currently fails.
    
    For now simply don't use it unless we're building with libstdc++.
