RFR Java types for anonymous C enums are generated with invalid class names.

[Samuel Audet]

C enums don't define a scope, so in my opinion whether they are 
anonymous or not, it doesn't make sense to try to wrap them in an 
interface or a class. Developers pay no attention to the name of these 
enums when using them in C, so why should they when using them from 
Java? Further, when they are anonymous, it forces users to give them a 
decent name, but since these don't have any names to start with, it 
becomes that much harder to figure out a way to refer to them! In 
JavaCPP, I just declare them as "public static final int" in the 
"global" namespace. Taking the example from the bug tracker:

typedef enum temp {
     ONE,
     TWO
} temp_t;

enum {
     Java,
     C,
     CPP,
     Python,
     Ruby
};

typedef enum {
     RED = 0xff0000,
     GREEN = 0x00ff00,
     BLUE = 0x0000ff
} color_t;

enum SIZE {
     XS,
     S,
     M,
     L,
     XL,
     XXL
};

JavaCPP maps this to:

/** enum temp */
public static final int
     ONE = 0,
     TWO = 1;

/** enum  */
public static final int
     Java = 0,
     C = 1,
     CPP = 2,
     Python = 3,
     Ruby = 4;

/** enum color_t */
public static final int
     RED = 0xff0000,
     GREEN = 0x00ff00,
     BLUE = 0x0000ff;

/** enum SIZE */
public static final int
     XS = 0,
     S = 1,
     M = 2,
     L = 3,
     XL = 4,
     XXL = 5;
