-# SYNOPSIS
-#
-# AC_PROG_SWIG([major.minor.micro])
-#
-# DESCRIPTION
-#
-# This macro searches for a SWIG installation on your system. If found you
-# should call SWIG via $(SWIG). You can use the optional first argument to
-# check if the version of the available SWIG is greater than or equal to
-# the value of the argument. It should have the format: N[.N[.N]] (N is a
-# number between 0 and 999. Only the first N is mandatory.)
-#
-# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
-# the swig package is this version number or higher.
-#
-# In configure.in, use as:
-#
-# AC_PROG_SWIG(1.3.17)
-# SWIG_ENABLE_CXX
-# SWIG_MULTI_MODULE_SUPPORT
-# SWIG_PYTHON

+# 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 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.

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

+ # taking place, the -pthread option has no effect ("argument unused
+ # 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

-# $(SWIG_PYTHON_OPT) contains all necessary SWIG options to generate code
-# for Python. Shadow classes are enabled unless the value of the optional
-# first argument is exactly 'no'. If you need multi module support
-# (provided by the SWIG_MULTI_MODULE_SUPPORT macro) use
-# $(SWIG_PYTHON_LIBS) to link against the appropriate library. It contains
-# the SWIG Python runtime library that is needed by the type check system
-# for example.
