All other such variables are described at the top of main Makefile,
for example:

  #
  # Define NO_LIBGEN_H if you don't have libgen.h.

I think that HAVE_PATHS_H should also have such one-line description.
By the way it the very first variable with HAVE_* rather than NEEDS_*
or NO_* name.

Why not

  +#ifdef HAVE_PATHS_H
  +#include <paths.h>
  +#endif
  +#ifndef _PATH_DEFPATH
  +#define _PATH_DEFPATH "/usr/local/bin:/usr/bin:/bin"
  +#endif

This way you are covered if some other header provides _PATH_DEFPATH.
Or is your way better?
