(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). -# -# 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.
