+Modifications to upstream libffi needed for the Mozilla build:
+* Clear INFO_DEPS so that builds don't fail when makeinfo isn't present.
+  - This can be removed if https://github.com/atgreen/libffi/issues/111 is fixed.
+* Various workarounds for pymake bugs.
+  - Once pymake support is fully deprecated, hunks 2 & 3 be safely removed.

+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILE_FLAG, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the current language's compiler
+#   or gives an error.  (Warnings, however, are ignored)
+#
+#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+#   success/failure.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this

+#
+# DESCRIPTION
+#
+#   Helper macro for AX_ENABLE_BUILDDIR.
+#
+#   The traditional way of starting a subdir-configure is running the script
+#   with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
+#   to rely on eval'ing $ac_configure_args however some old autoconf
+#   versions do not provide that. To ensure maximum portability of autoconf
+#   extension macros this helper can be AC_REQUIRE'd so that
+#   $ac_configure_args will alsways be present.
+#
+#   Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
+#   spoiled now and must be replaced by "eval + exit $?".
+#

+# SYNOPSIS
+#
+#   AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
+#
+# DESCRIPTION
+#
+#   If the current configure was run within the srcdir then we move all
+#   configure-files into a subdir and let the configure steps continue
+#   there. We provide an option --disable-builddir to suppress the move into
+#   a separate builddir.
+#
+#   Defaults:
+#
+#     $1 = $host (overridden with $HOST)
+#     $2 = Makefile.mk
+#     $3 = -all
+#
+#   This macro must be called before AM_INIT_AUTOMAKE. It creates a default
+#   toplevel srcdir Makefile from the information found in the created
+#   toplevel builddir Makefile. It just copies the variables and
+#   rule-targets, each extended with a default rule-execution that recurses
+#   into the build directory of the current "HOST". 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.

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+#
+# SYNOPSIS
+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".
+#
+#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+ * Only OpenBSD/m88k is currently supported; other platforms (such as

+ * - non-OpenBSD systems use an `outgoing parameter area' as part of the

+ *   release 3.6 onwards.  Supporting it should be as easy as taking it
+ *   into account when adjusting the stack, in the assembly code.

+ * - the logic deciding whether a function argument gets passed through
+ *   registers, or on the stack, has changed several times in OpenBSD in
+ *   edge cases (especially for structs larger than 32 bytes being passed
+ *   by value). The code below attemps to match the logic used by the
