* bignum.c (rb_big2ulong_pack): Use rb_integer_pack.
  (rb_big_aref): Call big2ulong with TRUE for "check" argument.
  It should be non-effective.

* bignum.c (big2ulong): "check" argument removed.
  (rb_big2ulong): Follow above change.
  (rb_big2long): Ditto.
  (rb_big_rshift): Ditto.
  (rb_big_aref): Ditto.

* ext/bigdecimal/bigdecimal.c (BigMath_s_exp): Fix for the cases when
  the argument x is not a BigDecimal.
  This change is based on the patch made by Garth Snyder.

* bignum.c (big2dbl): Use (BDIGIT)1 instead of 1UL.
  (bary_mul_normal): Remove a useless cast.

* lib/rubygems/ext/builder.rb (Gem::Ext::Builder.make): Pass
  DESTDIR via command line to override what's in MAKEFLAGS.  This
  fixes an installation problem under a package building
  environment where DESTDIR is specified in the (parent) command
  line. [Fixes GH-327]

	* gc.c (is_before_sweep): Add new helper function that check the object
	  is before sweep?
	* gc.c (rb_gc_force_recycle): Have to clear mark bit if object's slot
	  already ready to mainor sweep.

* bignum.c (bigand_int): Consider negative values.
  (bigor_int): The allocated bignum should have enough size
  to store long.
  This fixes (bignum fits in a BDIGIT) | (fixnum bigger than BDIGIT)
  on platforms which SIZEOF_BDIGITS < SIZEOF_LONG,
  such as LP64 with 32bit BDIGIT (no int128).
