If you look at the build process of this package, you'll see that it is
indeed an auto-generated file, and the 4 is coming from the detected
size of the int type at configuration time. And indeed, sizeof(int) == 2
on some platform (this is valid by the C99 standard). I will guess it is
used to define platform independent type with known size.

BTW, the ext2_types.h.in files read as:

        #if (@SIZEOF_INT@ == 4)
        typedef int          __s16;
        typedef unsigned int __u16;

However, I don't think this is the right list to discuss this.
