* alpha-tdep.c (heuristic_proc_desc): Stop examining the prologue
if we encounter a positive stack adjustment.
(find_proc_desc): If heuristic_fence_post is non-zero, use
heuristic_proc_start to determine the start of a function before
calling heuristic_proc_desc.
* coffread.c (coff_symtab_read): Change minimal symbol types
for C_LABEL symbols from mst_* to mst_file_*.
* config/m68k/sun3os4.mh (MMALLOC_CFLAGS): Define MMCHECK_FORCE to 1.
* configure.in: Handle error message from sun3 native ld when
configuring HLDFLAGS.
* configure: Regenerated with autoconf.
* c-valprint.c (c_value_print): Adjust value address by VALUE_OFFSET.
* cp-valprint.c (cp_print_value): Prevent gdb crashes by making sure
that the virtual base pointer from an user object still points to
accessible memory.
* dbxread.c (dbx_symfile_init): Initialize sym_stab_info to
clear the recently added header_files fields.
(dbx_symfile_finish): Free hfiles[i].vector to avoid storage leak.
