# http://autoconf-archive.cryp.to/ax_boost_filesystem.html
#
# 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
# 
# AUTHOR
# 
# 	Thomas Porschberg <thomas@randspringer.de> and Michael Tindal.
