I agree.

I think it would be helpful if there were some automated way of
reminding people to do that though.  Many people develop on systems
which define PATH_MAX but would want their code to build and work
correctly on systems that do not.

Is the current syntax-check system flexible enough to warn about uses
of PATH_MAX outside an #idfef PATH_MAX conditional?
