+# 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_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+# AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+# 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 $?".
+#
+# Example:
+#
+# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
+# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
+# eval $SHELL $ac_configure_args || 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 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_COMPILER_FLAGS, 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.
