+-#
+-# SYNOPSIS
+-#
+-# ACX_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.

++#
++# 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

++#
++# NOTE: You are assumed to not only compile your program with these flags,

++# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
++# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
++# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
++#
++# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the

++#
++# ACTION-IF-FOUND is a list of shell commands to run if a threads library

++ # However, older versions of Clang make a point of warning the user

++ # when source code is being compiled.
++ #
++ # Problem is, this is at odds with the way Automake and most other
++ # C build frameworks function, which is that the same flags used in
++ # compilation (CFLAGS) are also used in linking. Many systems
++ # supported by AX_PTHREAD require exactly this for POSIX threads
++ # support, and in fact it is often not straightforward to specify a
++ # flag that is used only in the compilation phase and not in
++ # linking. Such a scenario is extremely rare in practice.
++ #
++ # Even though use of the -pthread flag in linking would only print
++ # a warning, this can be a nuisance for well-run software projects
++ # that build with -Werror. So if the active version of Clang has
++ # this misfeature, we search for an option to squash it.
