# 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 to link with them as well. For example, you might link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threaded programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, 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
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# PTHREAD_CFLAGS.
#
# 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.

# doesn't hurt to check since this sometimes defines pthreads and

# (Note 2: On some systems, notably Darwin, -pthread is not needed
# to get POSIX threads support; the API is always present and

# during compilation"). They expect -pthread to be passed in only
# 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
