AX_COMPILER_FLAGS_CXXFLAGS([VARIABLE], [IS-RELEASE], [EXTRA-BASE-FLAGS], [EXTRA-YES-FLAGS])
Add warning flags for the C++ compiler to VARIABLE, which defaults to WARN_CXXFLAGS. VARIABLE is AC_SUBST-ed by this macro, but must be manually added to the CXXFLAGS variable for each target in the code base.
This macro depends on the environment set up by AX_COMPILER_FLAGS. Specifically, it uses the value of $ax_enable_compile_warnings to decide which flags to enable.
