I had no issues compiling a few different projects with this release,
however enabling this configure flag means that linking C++ with -static
does not work because libstdc++.a then requires VTV symbols. Also, note
that neither Fedora's nor (AFAICS) Debian's native gcc enable this
feature, so I don't know how much exposure it has received yet.
I would recommend rebuilding a 5.4.0-2 without this configure flag, and
releasing it as stable.

Until this is stable and mingw-based C++ packages have been recompiled,
-D_GLIBCXX_USE_CXX11_ABI=0 can be used as a workaround.
