             : #if defined(__i386__) || defined(__x86_64__)
In answer to your questions regarding 'LPC_IO' && 'LPC_MEMORY'; probably we have a simple initial patch here to convert hunks with this pattern:

```
#ifdef LPC_IO
 ....
#endif
#ifdef LPC_MEMORY
 ....
#endif
```

into,

```
#ifdef LPC_IO
 ....
#elif LPC_MEMORY
 ....
#endif
```

and that the defines for either should be at the top of the file with the guard `if defined(__i386__) || defined(__x86_64__)` modified to check if either is defined or just don't compile the file.
