    _______________________________________________________

Details:

The attached version of ax_cxx_compile_stdcxx_11.m4 has several changes:

The C++11 test code includes the "auto" keyword

AC_LANG_PUSH/POP rather than AC_LANG_ASSERT makes it more robust to use

An optional second argument makes it possible to test for C++11 and return the
result with an AC_DEFINE/AC_SUBST/AM_CONDITIONAL without erroring out if
support is not found.

This new version should be nearly backwards-compatible with the old; the
obvious exception being when compilers which implement a subset of C++11 not
including "auto" are used with codes for which that subset would have been
sufficient.
