ruby--ruby/ruby.h
matz e3a8c62630 * io.c (rb_io_mode_flags): both 'r+b' and 'rb+' should be allowed. 
* io.c (rb_io_mode_modenum): ditto.

* gc.c (rb_memerror): rename from mem_error, and exported.

* gc.c (Init_GC): pre-allocate NoMemoryError instance.

* object.c (convert_type): error message changed from "failed to
  convert" to "cannot convert", since it does not try to convert
  if an object does not respond to the converting method.

* eval.c (block_pass): convert Method to Proc using
  rb_check_convert_type().

* object.c (rb_check_convert_type): always convert T_DATA

* eval.c (rb_thread_cleanup): should not terminate main_thread by
  Fatal error.

* regex.c (is_in_list): need to not exclude NUL and NEWLINE.

* re.c (rb_reg_expr_str): wrong backslash escapement.

* re.c (rb_reg_expr_str): do not escape embedded space
  characters.

* marshal.c (w_object): T_DATA process patch from Joel VanderWerf
  <vjoel@PATH.Berkeley.EDU>.  This is temporary hack; it remains
  undocumented, and it will be removed when marshaling is
  re-designed.

* marshal.c (r_object): ditto.

* numeric.c (num_step): Integer#step is moved to Numeric#step;
  Fixnum#step is merged into this method.

* numeric.c (int_dotimes): Fixnum#times is merged.

* numeric.c (int_upto): Fixnum#upto is merged.

* numeric.c (int_downto): Fixnum#downto is merged.
