#
# SYNOPSIS
#
#   AX_CXX_LDFLAGS_STD_LANG(LD-FLAGS)
#
# DESCRIPTION
#
#   Append to LD-FLAGS the set of link-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 switches with `-Xlinker' so that Libtool doesn't
#   discard them (see Libtool's manual and `AC_LIBTOOLIZE_LDFLAGS').
