Sipke Vriend	0b5a78e2cd	Adjust lfs_dir_find return code to ensure 32 bit value. lfs_dir_find returns either a negative return code or a tag. For 32 bit machines with int as 32 bits this co-incides, but for smaller bit processors, we need to ensure a 32 bit value is returned so change the return type to lfs_stag_t.	2019-10-01 11:52:02 +10:00
