  * src/cache/ftccache.c (ftc_node_hash_unlink, ftc_node_hash_link) [FTC_CACHE_USE_LINEAR_HASHING]: Fix returned error code. Fix debugging messages. * src/type42/t42error.h: New file. * src/type42/t42drivr.c, src/type42/t42objs.c, src/type42/t42parse.c: Use t42 error codes. * src/type42/rules.mk: Updated. * src/base/ftnames.c: Include FT_INTERNAL_STREAM_H. Formatting, adding copyright messages.
