Seems like you really want PATH_MAX to be an autoconf test, and if
not, then test for MAXPATHLEN in <sys/param.h> and define PATH_MAX
in terms of MAXPATHLEN.

Basically, <machine/param.h> is by no means a standardized header, and
pulling it in causes all sorts of namespace pollution, so you wanna
use it only if you have to.
