commit cf3abf8aa612dc9750c00a4272bc3da46d54e57a
Author: Peter Simons <address@hidden>

    AX_GCC_VAR_ATTRIBUTE: fix spelling error
    
    https://savannah.gnu.org/patch/index.php?8815

commit 9e5ef8a7fa6f32dce37a9a340cef793254d2396b
Author: Joshua Judson Rosen <address@hidden>
Date:   Wed Dec 2 16:46:05 2015 -0500

    AX_CXX_COMPILE_STDCXX: don't break "make CXXFLAGS=..."
    
    Make C++ std-selection macros modify $(CXX), not $(CXXFLAGS).
    
    Using $(CXXFLAGS) prevents users from being able to
    rebuild with different CXXFLAGS (e.g.: to try out
    different optimisations or to change debug levels)
    unless they re-run ./configure with their CFLAGS.
    
    This is more like what the mainline Autoconf macros do
    (e.g.: AC_PROG_CC_C99, AC_PROG_CC_STD, etc. modify $(CC),
    not $(CCFLAGS)), presmuably for much the same reasons:
    if you need to specify a standard to the compiler,
    it doesn't really make sense to separate that from
    $(CC)/$(CXX) since $(CC)/$(CXX) aren't usable without it.

commit 401d6b8cefcc5bf3c1f6c35d76c589bb6b7387b0

    CXX_COMPILE_STDCXX: fix regression introduced in ccd1d4f54b
    
    AX_CXX_COMPILE_STDCXX doesn't set HAVE_CXX when [mandatory] is given as
    an argument. This bug has existed since commit ccd1d4f54b07b46b.
