Update.

	Fix a heap-corrupting bug.
	* io/ftw.c: Include <limits.h>.
	(PATH_MAX) [!defined PATH_MAX]: Define to 1024.
	(process_entry): Allocate enough space to hold the resulting
	file name.  Don't presume that 2*dirbufsize is enough.
	(ftw_startup): Always use PATH_MAX to compute buffer size, now that
	it is guaranteed to be defined.
