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_THREAD_LIB) 18# 19# And sets: 20# 21# HAVE_BOOST_THREAD 22# 23# LICENSE 24# 25# Copyright (c) 2009 Thomas Porschberg <thomas@randspringer.de> 26# Copyright (c) 2009 Michael Tindal 27# 28# Copying and distribution of this file, with or without modification, are 29# permitted in any medium without royalty provided the copyright notice 30# and this notice are preserved.
