++# SYNOPSIS
++#
++# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++#
++# DESCRIPTION
++#
++# This macro figures out how to build C programs using POSIX threads. It
++# sets the PTHREAD_LIBS output variable to the threads library and linker
++# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
++# flags that are needed. (The user can also force certain compiler
++# flags/libs to be tested by setting these environment variables.)
++#
++# Also sets PTHREAD_CC to any special C compiler that is needed for
++# multi-threaded programs (defaults to the value of CC otherwise). (This
++# is necessary on AIX to use the special cc_r compiler alias.)
++#
++# NOTE: You are assumed to not only compile your program with these flags,
++# but also link it with them as well. e.g. you should link with
++# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
++#
++# If you are only building threads programs, you may wish to use these
++# variables in your default LIBS, CFLAGS, and CC:
++#
++# LIBS="$PTHREAD_LIBS $LIBS"
++# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
++# CC="$PTHREAD_CC"
++#
++# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
++# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
++# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
++#
++# ACTION-IF-FOUND is a list of shell commands to run if a threads library
++# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
++# is not found. If ACTION-IF-FOUND is not specified, the default action
++# will define HAVE_PTHREAD.
++#
++# Please let the authors know if this macro fails on any platform, or if
++# you have any other suggestions or comments. This macro was based on work
++# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
++# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
++# Alejandro Forero Cuervo to the autoconf macro repository. We are also
++# grateful for the helpful feedback of numerous users.
