I don't understand?  If PATH_MAX is not defined it defaults to 0 in
preprocessor conditionals.  That's just the definition of the C
language.  This may break with a Classic C (pre-ISO C) preprocessor,
because basically *anything* can break on software that doesn't comply
with standards, but who really wants to support Classic C these days?
