Noteworthy changes in release 2012.04.07

Item posted by Peter Simons <simons> on Sat 07 Apr 2012 06:47:12 PM UTC.

The macro AX_CXX_COMPILE_STDCXX_11 has been added, which determines the compiler switches that need to be added to be passed in order to enable C++11 support in the compiler. See <https://savannah.gnu.org/patch/?7735> for further details.

The new macro AX_CXX_DELETE_METHOD has been added which checks whether the C++11 '= delete' syntax for suppressing undesired implicit methods is supported. Further details are at <https://savannah.gnu.org/patch/?7735>.

The macros AX_BOOST_CHRONO and AX_BOOST_LOCALE have been added which detect the Boost.Chrono and Boost.Locale library respectively. Further details are at <http://savannah.gnu.org/patch/?7721> and <http://savannah.gnu.org/patch/?7743>.

Support for automatic detection of dynamic libraries on Mac OS X (*.dylib) has been improved in all Boost macros. <http://savannah.gnu.org/patch/?7719> has further details.

Portability of AX_CHECK_LIBRARY has been improved so that the macro can be used with Autoconf versions prior to 2.64.

AX_GCC_ARCHFLAG has been extended to support new Intel/AMD CPUs. See <http://savannah.gnu.org/patch/?7707> for further details.

An endless recursion-bug in AX_COUNT_CPUS has been fixed. See <http://savannah.gnu.org/patch/?7697> for further details.

AX_LUA_LIBS has been fixed to work with Lua 5.2.
