ruby--ruby/node.h
matz 018837b84f * node.h (NODE_TYPESHIFT): allow 4 more bits for line numbers.
[ruby-talk:117841]

* ruby.h (FL_ABLE): nodes are not subject for flag operations.

* io.c (ARGF_FORWARD): should have specified argv explicitly,
  since we no longer have frame->argv saved.  [ruby-dev:24602]

* string.c (RESIZE_CAPA): check string attribute before modifying
  capacity member of string structure.  [ruby-dev:24594]

* ext/zlib/zlib.c (gzreader_gets): use memchr() to to gain
  performance.  [ruby-talk:117701]

* sprintf.c (rb_f_sprintf): raise ArgumentError for extra
  arguments, unless (digit)$ style used.

* io.c (rb_io_fptr_finalize): leave stdin/stdout/stderr open in
  interpreter termination.  [ruby-dev:24579]

* eval.c (frame_free): Guy Decoux solved the leak problem.
  Thanks.  [ruby-core:03549]
