AX_CXX_CXXFLAGS_STD_LANG(CXX-FLAGS)
@end smallexample

@majorheading 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').
