+ * inflow.c (new_tty): Temporarily ignore SIGTTOU when
+ disconnecting from controlling terminal, to avoid gdb hanging
+ on SVR4. Fixes bug reported by Oliver Okrongli.
+ * procfs.c (PROC_NAME_FMT): Change format to match default used
+ by system, as suggested by Oliver Okrongli.
+ * tm-68k.h (FRAME_FIND_SAVED_REGS): Apply missing parentheses
+ bug fix from Brent Townshend (bst%tt@cam.ORG).
+ * c-exp.y (nonempty_typelist): Fix memory overrun bug reported
+ by turlais@rechser.total.fr.
+ * dwarfread.c (decode_subscr_data): Fix bug in calculation of
+ length of non-zero lowerbound arrays. Bug fix from Peggy Fieland.
+ * objfiles.h (unlink_objfile): Add prototype.
+ * objfiles.c (unlink_objfile): Add function.
+ * objfiles.c (free_objfile): Call unlink_objfile.
+ * objfiles.c (allocate_objfile): Call unlink_objfile on newly
+ remapped objfiles. Bug reported by hahn@sunshine.labs.tek.com.
+ Also, discard old possibly bogus sf struct.
+ * symfile.c (symbol_file_add): Call init_entry_point_info() and
+ find_sym_fns() for remapped symbol files, in case of any changes
+ since the last mapping.

+ * findvar.c (read_relative_register_raw_bytes): use the raw size
+ of a register to bcopy, rather than the host's sizeof(CORE_ADDR).
