Agree that this is problem for 64-bit.

This is definitely one of the problems with porting to a 64-bit
platform.
One idea I had was to change the field initialization from:
public static final int sizeof = 12; // e.g., from GdkColor
to:
public static final int sizeof = OS.sizeof ("GdkColor");
Then the OS native code could simply return the correct value.
Of course there is also the preprocessing idea as floated in the
earlier 64-bit porting thread.
