#
# SYNOPSIS
#
#   AX_BOOST_WAVE
#
# DESCRIPTION
#
#   Test for Wave library from the Boost C++ libraries. The macro requires a
#   preceding call to AX_BOOST_BASE. Further documentation is available at
#   <http://randspringer.de/boost/index.html>.
#
#   This macro calls:
#
#     AC_SUBST(BOOST_WAVE_LIB)
#
#   And sets:
#
#     HAVE_BOOST_WAVE
