It is necessary to (at least partially) understand Autoconf, and have
some of the same Autoconf feature-checks that are in systemd's configure.ac.

See Autoconf documentation for details of how configure.ac is
preprocessed to create configure, and how the results of those checks
are passed through config.h{.in,} into the relevant compilation units.

This is fairly standard Autoconf usage, and is not systemd-specific.
