860can specify a directory with \`--prefix=DIR' to install in \`DIR/sbin',
861\`DIR/etc', etc.

1072dnl Useful macros for autoconf to check for ssp-patched gcc
1073dnl 1.0 - September 2003 - Tiago Sousa <mirage@kaotik.org>
1074dnl 1.1 - August 2006 - Ted Percival <ted@midg3t.net>
1075dnl     * Stricter language checking (C or C++)
1076dnl     * Adds GCC_STACK_PROTECT_LIB to add -lssp to LDFLAGS as necessary
1077dnl     * Caches all results
1078dnl     * Uses macros to ensure correct ouput in quiet/silent mode
1079dnl 1.2 - April 2007 - Ted Percival <ted@midg3t.net>
1080dnl     * Added GCC_STACK_PROTECTOR macro for simpler (one-line) invocation
1081dnl     * GCC_STACK_PROTECT_LIB now adds -lssp to LIBS rather than LDFLAGS
1082dnl
1083dnl About ssp:
1084dnl GCC extension for protecting applications from stack-smashing attacks
1085dnl http://www.research.ibm.com/trl/projects/security/ssp/
1086dnl
1087dnl Usage:
1088dnl Most people will simply call GCC_STACK_PROTECTOR.
1089dnl If you only use one of C or C++, you can save time by only calling the
1090dnl macro appropriate for that language. In that case you should also call
1091dnl GCC_STACK_PROTECT_LIB first.
1092dnl
1093dnl GCC_STACK_PROTECTOR
1094dnl Tries to turn on stack protection for C and C++ by calling the following
1095dnl three macros with the right languages.
1096dnl
1097dnl GCC_STACK_PROTECT_CC
1098dnl checks -fstack-protector with the C compiler, if it exists then updates
1099dnl CFLAGS and defines ENABLE_SSP_CC
1100dnl
1101dnl GCC_STACK_PROTECT_CXX
1102dnl checks -fstack-protector with the C++ compiler, if it exists then updates
1103dnl CXXFLAGS and defines ENABLE_SSP_CXX
1104dnl
1105dnl GCC_STACK_PROTECT_LIB
1106dnl adds -lssp to LIBS if it is available
1107dnl ssp is usually provided as part of libc, but was previously a separate lib
1108dnl It does not hurt to add -lssp even if libc provides SSP - in that case
1109dnl libssp will simply be ignored.

1578# SYNOPSIS
1579#
1580#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
1581#
1582# DESCRIPTION
1583#
1584#   This macro figures out how to build C programs using POSIX threads.
1585#   It sets the PTHREAD_LIBS output variable to the threads library and
1586#   linker flags, and the PTHREAD_CFLAGS output variable to any special
1587#   C compiler flags that are needed. (The user can also force certain
1588#   compiler flags/libs to be tested by setting these environment
1589#   variables.)
1590#
1591#   Also sets PTHREAD_CC to any special C compiler that is needed for
1592#   multi-threaded programs (defaults to the value of CC otherwise).
1593#   (This is necessary on AIX to use the special cc_r compiler alias.)
1594#
1595#   NOTE: You are assumed to not only compile your program with these
1596#   flags, but also link it with them as well. e.g. you should link
1597#   with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
1598#   $LIBS
1599#
1600#   If you are only building threads programs, you may wish to use
1601#   these variables in your default LIBS, CFLAGS, and CC:
1602#
1603#          LIBS="$PTHREAD_LIBS $LIBS"
1604#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
1605#          CC="$PTHREAD_CC"
1606#
1607#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
1608#   constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
1609#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
1610#
1611#   ACTION-IF-FOUND is a list of shell commands to run if a threads
1612#   library is found, and ACTION-IF-NOT-FOUND is a list of commands to
1613#   run it if it is not found. If ACTION-IF-FOUND is not specified, the
1614#   default action will define HAVE_PTHREAD.
1615#
1616#   Please let the authors know if this macro fails on any platform, or
1617#   if you have any other suggestions or comments. This macro was based
1618#   on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
1619#   (with help from M. Frigo), as well as ac_pthread and hb_pthread
1620#   macros posted by Alejandro Forero Cuervo to the autoconf macro
1621#   repository. We are also grateful for the helpful feedback of
1622#   numerous users.
