3283 | occupies 8 bytes. The first four bytes are the offset from the | |

3285 | this symbol. The second four bytes are the file offset to the | |
3286 | archive member which defines this symbol. If the second four bytes | |
3287 | are 0, then this is not actually a symbol definition, and it should | |
3288 | be ignored. | |
