-# SYNOPSIS
-#
-#   AX_BOOST_THREAD
-#
-# DESCRIPTION
-#
-#   Test for Thread 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_THREAD_LIB)
-#
-#   And sets:
-#
-#     HAVE_BOOST_THREAD
