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
