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.

+---------------------------
+
+--  * Dimensioned type
+
+--    A dimensioned type is a type (more accurately a first subtype) to which
+--    the aspect Dimension_System applies to.
+
+--      type Mks_Type is new Long_Long_Float
+--        with
+--         Dimension_System => (
+--          (Unit_Name => Meter,    Unit_Symbol => 'm',   Dim_Symbol => 'L'),
+--          (Unit_Name => Kilogram, Unit_Symbol => "kg",  Dim_Symbol => 'M'),
+--          (Unit_Name => Second,   Unit_Symbol => 's',   Dim_Symbol => 'T'),
+--          (Unit_Name => Ampere,   Unit_Symbol => 'A',   Dim_Symbol => 'I'),
+--          (Unit_Name => Kelvin,   Unit_Symbol => 'K',   Dim_Symbol => "Θ"),
+--          (Unit_Name => Mole,     Unit_Symbol => "mol", Dim_Symbol => 'N'),
+--          (Unit_Name => Candela,  Unit_Symbol => "cd",  Dim_Symbol => 'J'));
+
+--  * Dimensioned subtype
+
+--    A dimensioned subtype is a subtype directly defined from the dimensioned
+--    type and to which the aspect Dimension applies to.
+
+--      subtype Length is Mks_Type
+--        with
+--         Dimension => (Symbol => 'm',
+--           Meter =>  1,
+--           others => 0);
