I have a project configured via Autoconf, and I want to start using C++11 features in this project. How to have the “-std=gnu++0x” switch always enabled and support for the features checked while configuring?

You can do this with something like
AX_CHECK_COMPILE_FLAG, e.g.:(You need to be careful here that
AC_LANGis C++, not C at the point this is called because it’s possible to use gcc for C and something else for C++ or vice versa).
