Subject: 	* common/gdb_vecs.h: Moved here from ./gdb_vecs.h. 	*
 common/gdb_vecs.c: New file, contents from utils.c. 	* common/host-defs.h:
 New file, contents from defs.h. 	* utils.h: New file, contents from
 defs.h. 	* defs.h: Move all declarations of objects defined in utils.c 
 to utils.h (except QUIT() and related). 	#include "utils.h",
 "host-defs.h". 	* probe.h (probe_p): Move here from gdb_vecs.h. 
 * symfile.c: #include "probe.h" instead of "gdb_vecs.h". 	* utils.c
 (free_char_ptr_vec): Moved to common/gdb_vecs.c. 
 (dirnames_to_char_ptr_vec_append, dirnames_to_char_ptr_vec): Ditto. 	*
 Makefile.in (SFILES): Add common/gdb_vecs.c. 	(HFILES_NO_SRCDIR): Add
 common/gdb_vecs.h, common/host-defs.h, utils.h. 	(COMMON_OBS): Add
 gdb_vecs.o. 	(gdb_vecs.o): New rule.
