dnl Configure Options
dnl ===============================================
dnl Actual library checks come later, but pkg-config can be used here to grab
dnl external values to use as defaults for configure options
dnl Per the autoconf docs, --enable-*/--disable-* options should control
dnl features inherent to Pacemaker, while --with-*/--without-* options should
dnl control the use of external software. However, --enable-*/--disable-* may
dnl implicitly require additional external dependencies, and
dnl --with-*/--without-* may implicitly enable or disable features, so the
dnl line is blurry.
dnl
dnl We also use --with-* options for custom file, directory, and path
dnl locations, since autoconf does not provide an option type for those.

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:

* Andrew's code was originally written for OSes whose "struct tm" contains:

* Some OSes lack these, instead having:

:: "difference between UTC and local standard time"
* char *tzname[2] = { "...", "..." };
* I (David Lee) confess to not understanding the details. So my attempted
* generalisations for where their use is necessary may be flawed.
*
* 1. Does "difference between ..." subtract the same or opposite way?
* 2. Should it use "altzone" instead of "timezone"?
* 3. Should it use tzname[0] or tzname[1]? Interaction with timezone/altzone?
