# SYNOPSIS
#
# AX_ADD_FORTIFY_SOURCE
#
# DESCRIPTION
#
# Check whether -D_FORTIFY_SOURCE=2 can be added to CPPFLAGS without macro
# redefinition warnings or linker errors. Some distributions (such as
# Gentoo Linux) enable _FORTIFY_SOURCE globally in their compilers,
# leading to unnecessary warnings in the form of
#
# <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
# <built-in>: note: this is the location of the previous definition
#
# which is a problem if -Werror is enabled. This macro checks whether
# _FORTIFY_SOURCE is already defined, and if not, adds -D_FORTIFY_SOURCE=2
# to CPPFLAGS.
#
# Newer mingw-w64 msys2 package comes with a bug in
# headers-git-7.0.0.5546.d200317d-1. It broke -D_FORTIFY_SOURCE
# support, and would need -lssp or -fstack-protector. See
# https://github.com/msys2/MINGW-packages/issues/5803. Try to
# actually link it.

# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
#
# 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.
#
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# ===========================================================================
#
# SYNOPSIS
#
# AX_CHECK_GNU_MAKE()
#
# DESCRIPTION
#
# This macro searches for a GNU version of make. If a match is found:
#
# * The makefile variable `ifGNUmake' is set to the empty string, otherwise
# it is set to "#". This is useful for including a special features in a
# Makefile, which cannot be handled by other versions of make.
# * The variable `_cv_gnu_make_command` is set to the command to invoke
# GNU make if it exists, the empty string otherwise.
# * The variable `ax_cv_gnu_make_command` is set to the command to invoke
# GNU make by copying `_cv_gnu_make_command`, otherwise it is unset.
# * If GNU Make is found, its version is extracted from the output of
# `make --version` as the last field of a record of space-separated
# columns and saved into the variable `ax_check_gnu_make_version`.
#
# Here is an example of its use:
#
# Makefile.in might contain:
#
# # A failsafe way of putting a dependency rule into a makefile
# $(DEPEND):
# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
#
# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
# @ifGNUmake@ include $(DEPEND)
# @ifGNUmake@ endif
#
# Then configure.in would normally contain:
#
# AX_CHECK_GNU_MAKE()
# AC_OUTPUT(Makefile)
#
# Then perhaps to cause gnu make to override any other make, we could do
# something like this (note that GNU make always looks for GNUmakefile
# first):
#
# if ! test x$_cv_gnu_make_command = x ; then
# mv Makefile GNUmakefile
# echo .DEFAULT: > Makefile ;
# echo \ $_cv_gnu_make_command \$@ >> Makefile;
# fi
#
# Then, if any (well almost any) other make is called, and GNU make also
# exists, then the other make wraps the GNU make.

# 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 and PTHREAD_CXX to any special C compiler that is
# needed for multi-threaded programs (defaults to the value of CC
# respectively CXX otherwise). (This is necessary on e.g. AIX to use the
# special cc_r/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
# $PTHREAD_CXX $CXXFLAGS $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 $PTHREAD_CFLAGS"
# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
# CXX="$PTHREAD_CXX"
#
# 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. 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.

# (Note 1: This will need to be revisited if a system that Clang
# supports has POSIX threads in a separate library. This tends not
# to be the way of modern systems, but it's conceivable.)
# (Note 2: On some systems, notably Darwin, -pthread is not needed
# to get POSIX threads support; the API is always present and
# active. We could reasonably leave PTHREAD_CFLAGS empty. But
# -pthread does define _REENTRANT, and while the Darwin headers
# ignore this macro, third-party headers might not.)
# However, older versions of Clang make a point of warning the user
# that, in an invocation where only linking and no compilation is
# taking place, the -pthread option has no effect ("argument unused
# during compilation"). They expect -pthread to be passed in only
# when source code is being compiled.
#
# Problem is, this is at odds with the way Automake and most other
# C build frameworks function, which is that the same flags used in
# compilation (CFLAGS) are also used in linking. Many systems
# supported by AX_PTHREAD require exactly this for POSIX threads
# support, and in fact it is often not straightforward to specify a
# flag that is used only in the compilation phase and not in
# linking. Such a scenario is extremely rare in practice.
#
# Even though use of the -pthread flag in linking would only print
# a warning, this can be a nuisance for well-run software projects

# AX_TLS([action-if-found], [action-if-not-found])
#
# DESCRIPTION
#
# Provides a test for the compiler support of thread local storage (TLS)
# extensions. Defines TLS if it is found. Currently knows about C++11,
# GCC/ICC, and MSVC. I think SunPro uses the same as GCC, and Borland
# apparently supports either.

#
# SYNOPSIS
#
# AX_VALGRIND_DFLT(memcheck|helgrind|drd|sgcheck, on|off)
# AX_VALGRIND_CHECK()
#
# DESCRIPTION
#
# AX_VALGRIND_CHECK checks whether Valgrind is present and, if so, allows
# running `make check` under a variety of Valgrind tools to check for
# memory and threading errors.
#
# Defines VALGRIND_CHECK_RULES which should be substituted in your
# Makefile; and $enable_valgrind which can be used in subsequent configure
# output. VALGRIND_ENABLED is defined and substituted, and corresponds to
# the value of the --enable-valgrind option, which defaults to being
# enabled if Valgrind is installed and disabled otherwise. Individual
# Valgrind tools can be disabled via --disable-valgrind-<tool>, the
# default is configurable via the AX_VALGRIND_DFLT command or is to use
# all commands not disabled via AX_VALGRIND_DFLT. All AX_VALGRIND_DFLT
# calls must be made before the call to AX_VALGRIND_CHECK.
#
# If unit tests are written using a shell script and automake's
# LOG_COMPILER system, the $(VALGRIND) variable can be used within the
# shell scripts to enable Valgrind, as described here:
#
# https://www.gnu.org/software/gnulib/manual/html_node/Running-self_002dtests-under-valgrind.html
#
# Usage example:
#
# configure.ac:
#
# AX_VALGRIND_DFLT([sgcheck], [off])
# AX_VALGRIND_CHECK
#
# Makefile.am:
#
# @VALGRIND_CHECK_RULES@
# VALGRIND_SUPPRESSIONS_FILES = my-project.supp
# EXTRA_DIST = my-project.supp
#
# This results in a "check-valgrind" rule being added to any Makefile.am
# which includes "@VALGRIND_CHECK_RULES@" (assuming the module has been
# configured with --enable-valgrind). Running `make check-valgrind` in
# that directory will run the module's test suite (`make check`) once for
# each of the available Valgrind tools (out of memcheck, helgrind and drd)
# while the sgcheck will be skipped unless enabled again on the
# commandline with --enable-valgrind-sgcheck. The results for each check
# will be output to test-suite-$toolname.log. The target will succeed if
# there are zero errors and fail otherwise.
#
# Alternatively, a "check-valgrind-$TOOL" rule will be added, for $TOOL in
# memcheck, helgrind, drd and sgcheck. These are useful because often only
# some of those tools can be ran cleanly on a codebase.
#
# The macro supports running with and without libtool.

# lt~obsolete.m4 -- aclocal satisfying obsolete definitions. -*-Autoconf-*-

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.
