Nils Maier	22e414dbb0	Make AX_CXX_COMPILE_STDCXX_11 test for -stdlib=libc++ via std::shared_ptr ... The clang shipped with OSX XCode and clangs not build enabling libcpp, will default to the libstdc++ headers and lib installed on the system. In the OSX case, that libstdc++ is the one bundles with gcc-4.2, which is far too old to provide all required C++11 types, such as std::shared_ptr. Hence, the C++11 check should try to compile a program with a C++11 type and try -stdlib=libc++ if the default lib fails to compile said program.	2013-08-21 23:19:01 +02:00
Nils Maier	b888088dc3	Make the configure check for C++11 compiler mandatory ... Remove stray "dnl", so that mandatory actually works with (my) autoreconf.	2013-08-21 23:19:01 +02:00
