-# 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
+#
+#   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.

-# 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 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. We are also
-#   grateful for the helpful feedback of numerous users.

 Known issues
 ------------
-o If there are no replies for a forward or stub zone, for a reverse zone,

-  Only happens for (sub)zones that are blocked by default; e.g. 10.in-addr.arpa
 o If libevent is older (before 1.3c), unbound will exit instead of reload
   on sighup. On a restart 'did not exit gracefully last time' warning is 
   printed. Perform ./configure --with-libevent=no or update libevent, rerun 
   configure and recompile unbound to make sighup work correctly.
-  It is strongly suggested to use a recent version of libevent.

-The DNS64 code was written by Viagenie, 2009, by Simon Perrault as part
-of the Ecdysis project.  The code is copyright by them, and has the BSD
-license (see the dns64/dns64.c file).
-
-To enable DNS64 functionality in Unbound, two directives in unbound.conf must
-be edited:
-
-1. The "module-config" directive must start with "dns64". For example:
-
-    module-config: "dns64 validator iterator"
-
-If you're not using DNSSEC then you may remove "validator".
-
-2. The "dns64-prefix" directive indicates your DNS64 prefix. For example:
-
-    dns64-prefix: 64:FF9B::/96
-
-The prefix must be a /96 or shorter.
-
-To test that things are working right, perform a query against Unbound for a
-domain name for which no AAAA record exists. You should see a AAAA record in
-the answer section. The corresponding IPv6 address will be inside the DNS64
-prefix. For example:
