I know how macros work. :-)

Exactly. How do I test the value of the macro, given that it's used as
a component of a path (to the spool directory, for example)? The only
thing I can think of is to use expansion in the value for spool_directory,
and to expand to a syntactically invalid pathname if the default value
of the macro hasn't been overridden. Syntactically invalid pathnames
are quite hard to produce. :-)
