This is sort of backwards. realpath(3) is standard in POSIX.1.2001 and
spells the limit {PATH_MAX}. MAXPATHLEN has the advantage of being
explictly unportable, but we (mainly imp) usually replace MAXPATHLEN
by PATH_MAX. (The compile-time constant PATH_MAX should not be confused
with the POSIX limit {PATH_MAX} or used if it is not defined, but
MAXPATHLEN is always defined on BSD systems.)
