5# SYNOPSIS
6#
7#   AX_BOOST_SYSTEM
8#
9# DESCRIPTION
10#
11#   Test for System library from the Boost C++ libraries. The macro requires
12#   a preceding call to AX_BOOST_BASE. Further documentation is available at
13#   <http://randspringer.de/boost/index.html>.
14#
15#   This macro calls:
16#
17#     AC_SUBST(BOOST_SYSTEM_LIB)
18#
19#   And sets:
20#
21#     HAVE_BOOST_SYSTEM
