+We use negative numbers for the compiler, and leave the possitive
+numbers to match the Microsoft numbers:
+
+-1	An Primary Expression was parsed, when a Type was expected.
+	This happens because my parser knowledge is limited, and I
+	am not good at writing grammars.  It is still an error,
+	but if I were smarter, I would have found a Bison/Yacc way
+	of handling it.
+
+-2	Internal error, an interface is being defined inside an
+	interface (This should never happen).
+
+-3      Constant type is not one of sbyte, byte, short, ushort, int,
+	uint, long, ulong, char, float, double, decimal, bool, string, enum
+	or null type. 
+
+-5      A search for a name on a Type returned matches that contain
+	methods and non-methods.  They have the same name, and I do
+	not know how this is possible to begin with.
+
+-6      Generic internal compiler error.
+
+-7      Internal compiler error/library error: no default constructor
+	for a built-in type.  Ie, decimal (int 32)
+
+-8	User-defined conversion cannot convert from or to object type.
+
+-9	User-defined conversion cannot convert from or to an interface type.
+
+-10	User-defined conversion cannot convert between types that derive 
+	from each other.
+
+-11	Delegate creation expression takes only one argument
+
+-12     More than one integral conversion exists for the type on a
+	switch statement.
+
+-13	No return with a value found.  Warning, since we currently
+	do not perform flow analysis, and can not tell whether a
+	ret is required or not.
+
+-14     Invalid number passed to probe
+
+-15	Can not locate default assembly path
+
+-16	Can not use System.Enum.ToObject (type, ConstantValue) with
+	user defined types.
+
+-17     A type has already been defined (try --nostdlib)
+
+-18	Do not know how to generate debugging information for this platform.
+
+-19     Can not find required utility function in the core libraries.
