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