	dnl Hardening flags
	dnl
	dnl The prime control of whether to apply (targeted) hardening build flags and
	dnl which ones is --{enable,disable}-hardening option passed to ./configure:
	dnl
	dnl --enable-hardening=try (default):
	dnl depending on whether any of CFLAGS_HARDENED_EXE, LDFLAGS_HARDENED_EXE,
	dnl CFLAGS_HARDENED_LIB or LDFLAGS_HARDENED_LIB environment variables
	dnl (see below) is set and non-null, all these custom flags (even if not
	dnl set) are used as are, otherwise the best effort is made to offer
	dnl reasonably strong hardening in several categories (RELRO, PIE,
	dnl "bind now", stack protector) according to what the selected toolchain
	dnl can offer
	dnl
	dnl --enable-hardening:
	dnl same effect as --enable-hardening=try when the environment variables
	dnl in question are suppressed
	dnl
	dnl --disable-hardening:
	dnl do not apply any targeted hardening measures at all
	dnl
	dnl The user-injected environment variables that regulate the hardening in
	dnl default case are as follows:
	dnl
	dnl * CFLAGS_HARDENED_EXE, LDFLAGS_HARDENED_EXE
	dnl compiler and linker flags (respectively) for daemon programs
	dnl (pacemakerd, pacemaker-attrd, pacemaker-controld, pacemaker-execd,
	dnl pacemaker-based, pacemaker-fenced, pacemaker-remoted,
	dnl pacemaker-schedulerd)
	dnl
	dnl * CFLAGS_HARDENED_LIB, LDFLAGS_HARDENED_LIB
	dnl compiler and linker flags (respectively) for libraries linked
	dnl with the daemon programs
	dnl
	dnl Note that these are purposedly targeted variables (addressing particular
	dnl targets all over the scattered Makefiles) and have no effect outside of
	dnl the predestined scope (e.g., CLI utilities). For a global reach,
	dnl use CFLAGS, LDFLAGS, etc. as usual.
	dnl
	dnl For guidance on the suitable flags consult, for instance:
	dnl https://fedoraproject.org/wiki/Changes/Harden_All_Packages#Detailed_Harden_Flags_Description
	dnl https://owasp.org/index.php/C-Based_Toolchain_Hardening#GCC.2FBinutils
