(Otherwise, we should probably explicitly disable determining HAVE_CXX0X and CXXFLAGS_CXX11 for MinGW in configure.ac.)

MinGW: C++11 perfect forwarding support is broken
So we have weird breakage on MinGW: in configure phase i686-w64-mingw32-g++ reports back success for that check: configure:15247: checking whether ccache i686-w64-mingw32-g++ supports C++11 perfect forwarding configure:15275: ccache i686-w64-mingw32-g++ -c -std=gnu++0x conftest.cpp 5 configure:15275: $? = 0 configure:15288: result: yes setting HAVE_CXX11_PERFECT_FORWARDING to 1 and then failing in compile phase with the question: what's that [1]. Workaround for now is uncomment export lines in configure.ac, then it s happy again [2] Environment: newest OpenSUSE, david@numptyi686-w64-mingw32-g++ --version i686-w64-mingw32-g++ (GCC) 4.7.2 [1] https://ci.idaia.de/job/LO-Mingw64/142/console [2] https://ci.idaia.de/job/LO-Mingw64/151/console David ___ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
