      2  * POSIX allows PATH_MAX to not be defined, see
      3  * http://pubs.opengroup.org/onlinepubs/9699919799/functions/sysconf.html;
      4  * the GNU Hurd is an example of a system not having it.
      5  *
      6  * Arguably, it would be better to test sysconf(_SC_PATH_MAX),
      7  * but since the individual *.c files include "config.h" before
      8  * <limits.h>, overriding an excessive value of PATH_MAX from
      9  * "config.h" is impossible anyway, so for now, the simplest
     10  * fix is to provide a value only on systems not having any.
     11  * So far, we encountered no system defining PATH_MAX to an
     12  * impractically large value, even though POSIX explicitly
     13  * allows that.
     14  *
     15  * The real fix would be to replace all static buffers of size
     16  * PATH_MAX by dynamically allocated buffers.  But that is
     17  * somewhat intrusive because it touches several files and
     18  * because it requires changing struct mlink in mandocdb.c.
     19  * So i'm postponing that for now.
