You can override the +#   auto-dection through `config.guess` and build-time of course, as in +# +#     make HOST=i386-mingw-cross +# +#   which can of course set at configure time as well using +# +#     configure --host=i386-mingw-cross +# +#   After the default has been created, additional rules can be appended +#   that will not just recurse into the subdirectories and only ever exist +#   in the srcdir toplevel makefile - these parts are read from the $2 = +#   Makefile.mk file +# +#   The automatic rules are usually scanning the toplevel Makefile for lines +#   like '#### $host |$builddir' to recognize the place where to recurse +#   into. Usually, the last one is the only one used. However, almost all +#   targets have an additional "*-all" rule which makes the script to +#   recurse into _all_ variants of the current HOST (!!) setting. The "-all" +#   suffix can be overriden for the macro as well. +# +#   a special rule is only given for things like "dist" that will copy the +#   tarball from the builddir to the sourcedir (or $(PUB)) for reason of +#   convenience. +# +# LICENSE +# +#   Copyright (c) 2009 Guido U.

After calling AX_EXTEND_SRCDIR, +#   $srcdir will be set to "../../i3-4.12". +# +#   The result of extending $srcdir is that filenames (e.g. in the output of +#   the "backtrace" gdb command) will include one more path component of the +#   absolute source path. The additional path component makes it easy for +#   users to recognize which files belong to the PACKAGE, and -- provided a +#   dist tarball was unpacked -- which version of PACKAGE was used. +# +#   As an example, in "backtrace", you will see: +# +#     #0  main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187 +# +#   instead of: +# +#     #0  main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187 +# +#   In case your code uses the __FILE__ preprocessor directive to refer to +#   the filename of the current source file (e.g. in debug messages), using +#   the extended path might be undesirable. For this purpose, +#   AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS, +#   which can be added to AM_CPPFLAGS in Makefile.am in order to define the +#   preprocessor directive STRIPPED__FILE__. As an example, when compiling +#   the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to +#   "main.c". +# +#   There are some caveats: When $srcdir is "." (i.e. when ./configure was +#   called instead of ../configure in a separate build directory), +#   AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will +#   not be achieved because of the way automake specifies file paths: +#   automake defines COMPILE to use "`test -f '$source' || echo +#   '\$(srcdir)/'`$source" in order to prefer files in the current directory +#   over specifying $srcdir explicitly. +# +#   The AX_EXTEND_SRCDIR author is not aware of any way to influence this +#   automake behavior. Patches very welcome. +# +#   To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by adding +#   the following code to configure.ac: +# +#     AX_ENABLE_BUILDDIR +#     dnl ... +#     AX_EXTEND_SRCDIR +# +#   Then also add this bit to Makefile.am (if you wish to use +#   STRIPPED__FILE__ in your code): +# +#     AM_CPPFLAGS = @AX_EXTEND_SRCDIR_CPPFLAGS@ +# +# LICENSE +# +#   Copyright (c) 2016 Michael Stapelberg <michael@i3wm.org> +# +#   Copying and distribution of this file, with or without modification, are +#   permitted in any medium without royalty provided the copyright notice +#   and this notice are preserved.

(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 to link with them as well. For example, you might link with +#   $PTHREAD_CC $CFLAGS $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 $PTHREAD_CFLAGS" +#     CC="$PTHREAD_CC" +# +#   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.
