Check in a pristine copy of GCC 4.8.1.

The copy of GCC that we use for Android is still not working for
mingw. Rather than finding all the differences that have crept into
our GCC, just check in a copy from
ftp://ftp.gnu.org/gnu/gcc/gcc-4.9.3/gcc-4.8.1.tar.bz2.

GCC 4.8.1 was chosen because it is what we have been using for mingw
thus far, and the emulator doesn't yet work when upgrading to 4.9.

+--  Heapsort generic package using formal procedures
+
+--  This package provides a generic heapsort routine that can be used with
+--  different types of data.
+
+--  See also GNAT.Heap_Sort, a version that works with subprogram access
+--  parameters, allowing code sharing. The generic version is slightly more
+--  efficient but does not allow code sharing and has an interface that is
+--  more awkward to use.
+
+--  There is also GNAT.Heap_Sort_A, which is now considered obsolete, but
+--  was an older version working with subprogram parameters. This version
+--  is retained for backwards compatibility with old versions of GNAT.
+
+--  This heapsort algorithm uses approximately N*log(N) compares in the
+--  worst case and is in place with no additional storage required. See
+--  the body for exact details of the algorithm used.
+
+generic
+   --  The data to be sorted is assumed to be indexed by integer values from
+   --  1 to N, where N is the number of items to be sorted. In addition, the
+   --  index value zero is used for a temporary location used during the sort.
+
+   with procedure Move (From : Natural; To : Natural);
+   --  A procedure that moves the data item with index value From to the data
+   --  item with index value To (the old value in To being lost). An index
+   --  value of zero is used for moves from and to a single temporary location.
+   --  For best efficiency, this routine should be marked as inlined.
+
+   with function Lt (Op1, Op2 : Natural) return Boolean;
+   --  A function that compares two items and returns True if the item with
+   --  index Op1 is less than the item with Index Op2, and False if the Op1
+   --  item is greater than the Op2 item. If the two items are equal, then
+   --  it does not matter whether True or False is returned (it is slightly
+   --  more efficient to return False). For best efficiency, this routine
+   --  should be marked as inlined.
+
+   --  Note on use of temporary location
+
+   --  There are two ways of providing for the index value zero to represent
+   --  a temporary value. Either an extra location can be allocated at the
+   --  start of the array, or alternatively the Move and Lt subprograms can
+   --  test for the case of zero and treat it specially. In any case it is
+   --  desirable to specify the two subprograms as inlined and the tests for
+   --  zero will in this case be resolved at instantiation time.
+
+package GNAT.Heap_Sort_G is
+   pragma Pure;
+
+   procedure Sort (N : Natural);
+   --  This procedures sorts items in the range from 1 to N into ascending
+   --  order making calls to Lt to do required comparisons, and Move to move
+   --  items around. Note that, as described above, both Move and Lt use a
+   --  single temporary location with index value zero. This sort is not
+   --  stable, i.e. the order of equal elements in the input is not preserved.
