	1075	dnl * Stricter language checking (C or C++)
	1076	dnl * Adds GCC_STACK_PROTECT_LIB to add -lssp to LDFLAGS as necessary
	1077	dnl * Caches all results
	1078	dnl * Uses macros to ensure correct ouput in quiet/silent mode
	1079	dnl 1.2 - April 2007 - Ted Percival <ted@midg3t.net>
	1080	dnl * Added GCC_STACK_PROTECTOR macro for simpler (one-line) invocation

	1084	dnl GCC extension for protecting applications from stack-smashing attacks
	1085	dnl http://www.research.ibm.com/trl/projects/security/ssp/
	1086	dnl
	1087	dnl Usage:
[120]	1088	dnl Most people will simply call GCC_STACK_PROTECTOR.
	1089	dnl If you only use one of C or C++, you can save time by only calling the
	1090	dnl macro appropriate for that language. In that case you should also call
	1091	dnl GCC_STACK_PROTECT_LIB first.
[1]	1092	dnl
[120]	1093	dnl GCC_STACK_PROTECTOR
	1094	dnl Tries to turn on stack protection for C and C++ by calling the following
	1095	dnl three macros with the right languages.
	1096	dnl
[1]	1097	dnl GCC_STACK_PROTECT_CC
	1098	dnl checks -fstack-protector with the C compiler, if it exists then updates
	1099	dnl CFLAGS and defines ENABLE_SSP_CC
	1100	dnl
[120]	1101	dnl GCC_STACK_PROTECT_CXX
	1102	dnl checks -fstack-protector with the C++ compiler, if it exists then updates
	1103	dnl CXXFLAGS and defines ENABLE_SSP_CXX
	1104	dnl
	1105	dnl GCC_STACK_PROTECT_LIB
	1106	dnl adds -lssp to LIBS if it is available
	1107	dnl ssp is usually provided as part of libc, but was previously a separate lib
	1108	dnl It does not hurt to add -lssp even if libc provides SSP - in that case
	1109	dnl libssp will simply be ignored.

	1573	# SYNOPSIS
	1574	#
	1575	# ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
	1576	#
	1577	# DESCRIPTION
	1578	#
	1579	# This macro figures out how to build C programs using POSIX threads.
	1580	# It sets the PTHREAD_LIBS output variable to the threads library and
	1581	# linker flags, and the PTHREAD_CFLAGS output variable to any special
	1582	# C compiler flags that are needed. (The user can also force certain
	1583	# compiler flags/libs to be tested by setting these environment
	1584	# variables.)
	1585	#
	1586	# Also sets PTHREAD_CC to any special C compiler that is needed for
	1587	# multi-threaded programs (defaults to the value of CC otherwise).
	1588	# (This is necessary on AIX to use the special cc_r compiler alias.)
	1589	#
	1590	# NOTE: You are assumed to not only compile your program with these
	1591	# flags, but also link it with them as well. e.g. you should link
	1592	# with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
	1593	# $LIBS
	1594	#
	1595	# If you are only building threads programs, you may wish to use
	1596	# these variables in your default LIBS, CFLAGS, and CC:
	1597	#
	1598	# LIBS="$PTHREAD_LIBS $LIBS"
	1599	# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
	1600	# CC="$PTHREAD_CC"
	1601	#
	1602	# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
	1603	# constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
	1604	# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
	1605	#
	1606	# ACTION-IF-FOUND is a list of shell commands to run if a threads
	1607	# library is found, and ACTION-IF-NOT-FOUND is a list of commands to
	1608	# run it if it is not found. If ACTION-IF-FOUND is not specified, the
	1609	# default action will define HAVE_PTHREAD.
	1610	#
	1611	# Please let the authors know if this macro fails on any platform, or
	1612	# if you have any other suggestions or comments. This macro was based
	1613	# on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
	1614	# (with help from M. Frigo), as well as ac_pthread and hb_pthread
	1615	# macros posted by Alejandro Forero Cuervo to the autoconf macro
	1616	# repository. We are also grateful for the helpful feedback of
	1617	# numerous users.
