Rename AC_ prefixes to AX_ (only in names of aa macros!).

+# SYNOPSIS
+#
+#   AX_CXX_CXXFLAGS_STD_LANG(CXX-FLAGS)
+#
+# DESCRIPTION
+#
+#   Append to variable CXX-FLAGS the set of compile-time flags that should
+#   be passed to the C++ compiler in order to enable use of C++ features as
+#   defined in the ANSI C++ standard (eg. use of standard iostream classes
+#   in the `std' namespace, etc.). Note that if you use GNU Libtool you may
+#   need to prefix each of those flags with `-Xcompiler' so that Libtool
+#   doesn't discard them (see Libtool's manual and `AC_LIBTOOLIZE_CFLAGS').
