Focusing on the diskimg library this time, which deals with a lot of filesystem structures that have specific widths. This is still a bit lax in places, e.g. using "long" for lengths. Should either specify a bit width or use di_off_t. Also, added "override" keyword where appropriate. Also, bumped library version to 5.0.0.

|
|
* Some notes on ASPI stuff:
|
|
* - The Nero ASPI provides an interface for IDE hard drives. It also
|
|
* throws in a couple of mystery devices on a host adapter at the end.
|
|
* It has "unknown" device type and doesn't respond to SCSI device
|
|
* inquiries, so it's easy to ignore.
|
|
* - The Win98 generic ASPI only finds CD-ROM drives on the IDE bus.
