# 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').
