	1106	dnl 1.2 - April 2007 - Ted Percival <ted@midg3t.net>

	1112	dnl http://www.research.ibm.com/trl/projects/security/ssp/
	1113	dnl
	1114	dnl Usage:
[120]	1115	dnl Most people will simply call GCC_STACK_PROTECTOR.
	1116	dnl If you only use one of C or C++, you can save time by only calling the
	1117	dnl macro appropriate for that language. In that case you should also call
	1118	dnl GCC_STACK_PROTECT_LIB first.

	1665	# SYNOPSIS
	1666	#
	1667	# ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
	1668	#
	1669	# DESCRIPTION
	1670	#
	1671	# This macro figures out how to build C programs using POSIX threads.
	1672	# It sets the PTHREAD_LIBS output variable to the threads library and
	1673	# linker flags, and the PTHREAD_CFLAGS output variable to any special
	1674	# C compiler flags that are needed. (The user can also force certain
	1675	# compiler flags/libs to be tested by setting these environment
	1676	# variables.)
	1677	#
	1678	# Also sets PTHREAD_CC to any special C compiler that is needed for
	1679	# multi-threaded programs (defaults to the value of CC otherwise).
	1680	# (This is necessary on AIX to use the special cc_r compiler alias.)
	1681	#
	1682	# NOTE: You are assumed to not only compile your program with these
	1683	# flags, but also link it with them as well. e.g. you should link
	1684	# with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
	1685	# $LIBS
	1686	#
	1687	# If you are only building threads programs, you may wish to use
	1688	# these variables in your default LIBS, CFLAGS, and CC:
	1689	#
	1690	# LIBS="$PTHREAD_LIBS $LIBS"
	1691	# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
	1692	# CC="$PTHREAD_CC"
	1693	#
	1694	# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
	1695	# constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
	1696	# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
	1697	#
	1698	# ACTION-IF-FOUND is a list of shell commands to run if a threads
	1699	# library is found, and ACTION-IF-NOT-FOUND is a list of commands to
	1700	# run it if it is not found. If ACTION-IF-FOUND is not specified, the
	1701	# default action will define HAVE_PTHREAD.
	1702	#
	1703	# Please let the authors know if this macro fails on any platform, or
	1704	# if you have any other suggestions or comments. This macro was based
	1705	# on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
	1706	# (with help from M. Frigo), as well as ac_pthread and hb_pthread
	1707	# macros posted by Alejandro Forero Cuervo to the autoconf macro
	1708	# repository. We are also grateful for the helpful feedback of
	1709	# numerous users.
