# SYNOPSIS
#
# AX_ADD_FORTIFY_SOURCE
#
# DESCRIPTION
#
# Check whether -D_FORTIFY_SOURCE=2 can be added to CPPFLAGS without macro
# redefinition warnings. 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.

# SYNOPSIS
#
# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
# For every FLAG1, FLAG2 it is checked whether the compiler works with the
# flag. If it does, the flag is added FLAGS-VARIABLE
#
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
# CFLAGS) is used. During the check the flag is always added to the
# current language's flags.
#
# 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: This macro depends on the AX_APPEND_FLAG and
# AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
# AX_APPEND_LINK_FLAGS.

# SYNOPSIS
#
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
#
# DESCRIPTION
#
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
# added in between.
#
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
# FLAG.

#
# SYNOPSIS
#
# AX_REQUIRE_DEFINED(MACRO)
#
# DESCRIPTION
#
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
# been defined and thus are available for use. This avoids random issues
# where a macro isn't expanded. Instead the configure script emits a
# non-fatal:
#
# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
#
# It's like AC_REQUIRE except it doesn't expand the required macro.
#
# Here's an example:
#
# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
