-#
-# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on

-# If EXTRA-FLAGS is defined, it is added to the current language's default

-# 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.
-#
-# INPUT gives an alternative input source to AC_COMPILE_IFELSE.

-# SYNOPSIS
-#
-# AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
-#
-# DESCRIPTION
-#
-# This macro compares two version strings. Due to the various number of
-# minor-version numbers that can exist, and the fact that string
-# comparisons are not compatible with numeric comparisons, this is not
-# necessarily trivial to do in a autoconf script. This macro makes doing
-# these comparisons easy.
-#
-# The six basic comparisons are available, as well as checking equality
-# limited to a certain number of minor-version levels.
-#
-# The operator OP determines what type of comparison to do, and can be one
-# of:
-#
-# eq - equal (test A == B)
-# ne - not equal (test A != B)
-# le - less than or equal (test A <= B)
-# ge - greater than or equal (test A >= B)
-# lt - less than (test A < B)
-# gt - greater than (test A > B)
-#
-# Additionally, the eq and ne operator can have a number after it to limit
-# the test to that number of minor versions.
-#
-# eq0 - equal up to the length of the shorter version
-# ne0 - not equal up to the length of the shorter version
-# eqN - equal up to N sub-version levels
-# neN - not equal up to N sub-version levels
-#
-# When the condition is true, shell commands ACTION-IF-TRUE are run,
-# otherwise shell commands ACTION-IF-FALSE are run. The environment
-# variable 'ax_compare_version' is always set to either 'true' or 'false'
-# as well.
-#
-# Examples:
-#
-# AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
-# AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
-#
-# would both be true.
-#
-# AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
-# AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
-#
-# would both be false.
-#
-# AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
-#
-# would be true because it is only comparing two minor versions.
-#
-# AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
-#
-# would be true because it is only comparing the lesser number of minor
-# versions of the two values.
-#
-# Note: The characters that separate the version numbers do not matter. An
-# empty string is the same as version 0. OP is evaluated by autoconf, not
-# configure, so must be a string, not a variable.
-#
-# The author would like to acknowledge Guido Draheim whose advice about
-# the m4_case and m4_ifvaln functions make this macro only include the
-# portions necessary to perform the specific comparison specified by the
-# OP argument in the final configure script.

-# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
-#
-# DESCRIPTION
-#
-# Check for baseline language coverage in the compiler for the specified
-# version of the C++ standard. If necessary, add switches to CXX and
-# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
-# or '14' (for the C++14 standard).
-#
-# The second argument, if specified, indicates whether you insist on an
-# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-# -std=c++11). If neither is specified, you get whatever works, with
-# preference for an extended mode.
-#
-# The third argument, if specified 'mandatory' or if left unspecified,
-# indicates that baseline support for the specified C++ standard is
-# required and that the macro should error out if no mode with that
-# support is found. If specified 'optional', then configuration proceeds
-# regardless, after defining HAVE_CXX${VERSION} if and only if a
-# supporting mode is found.

-#
-# This macro figures out what libraries are required on this platform to

-#
-# The common cases are not to need any extra libraries, or to need
-# -lsocket and -lnsl. We need to avoid linking with libnsl unless we need
-# it, though, since on some OSes where it isn't necessary it will totally
-# break networking. Unisys also includes gethostbyname() in libsocket but
-# needs libnsl for socket().

-# SYNOPSIS
-#
-# AX_PROG_CC_FOR_BUILD
-#
-# DESCRIPTION
-#
-# This macro searches for a C compiler that generates native executables,
-# that is a C compiler that surely is not a cross-compiler. This can be
-# useful if you have to generate source code at compile-time like for
-# example GCC does.
-#
-# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
-# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
-# The value of these variables can be overridden by the user by specifying
-# a compiler with an environment variable (like you do for standard CC).
-#
-# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
-# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
-# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
-# substituted in the Makefile.
