+# 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.
