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 and PTHREAD_CXX to any special C compiler that is -+# needed for multi-threaded programs (defaults to the value of CC -+# respectively CXX otherwise). (This is necessary on e.g. AIX to use the -+# special cc_r/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 -+# $PTHREAD_CXX $CXXFLAGS $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 $PTHREAD_CFLAGS" -+# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" -+# CC="$PTHREAD_CC" -+# CXX="$PTHREAD_CXX" -+# -+# 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. -+# -+# Updated for Autoconf 2.68 by Daniel Richard G. -+# -+# LICENSE -+# -+# Copyright (c) 2008 Steven G.
