I think the correct fix would be to ensure that "size_t" is defined.
"size_t" is defined by <sys/types.h>, <unistd.h> and/or <stdio.h>, depending
on platform, and all are included before any attempt is made to hack around
MAXPATHLEN. So what's going on on Hurd? Is there a bug that "config.h"
is not included first?
