Ah, I didn't know that.  I thought PATH_MAX was supposed to be undefined
in that case.  (Which implementations are these?  It sounds to me like
such implementations are broken anyway -- do we need to cater to them?)

The autoconf test would be better.  I doubt whether the problem is
limited to Sun; it's probably endemic to SVR4.
