ruby--ruby/ext/tcltklib/tcltklib.c
usa b469f3155a * array.c (ary_alloc), dir.c (dir_s_alloc), eval.c (thgroup_s_alloc), 
file.c (rb_stat_s_alloc), hash.c (hash_alloc), io.c (io_alloc),
  object.c (rb_module_s_alloc, rb_class_allocate_instance),
  re.c (match_alloc, rb_reg_s_alloc), string.c (str_alloc),
  time.c (time_s_alloc), ext/digest/digest.c (rb_digest_base_alloc),
  ext/tcltklib/tcltklib.c (ip_alloc),
  ext/win32ole/win32ole.c (fole_s_allocate, fev_s_allocate)
  : add prototype to get rid of VC++ warnings.

* ext/sdbm/init.c (fsdbm_alloc): allocator takes only one argument.
