From: Stephane Marchesin
Subject: Re: [SDL] Problem compiling SDL 1.2.7
- there is a bug that was introduced in the kernel headers for 2.6.9
which is fixed in 2.6.10. This bug *will* byte when compiling the cdrom
subsystem. A patch that works around this bug is attached. Note that
users affected are not those running 2.6.9, but those using the 2.6.9
kernel headers for their system (i.e. whose libc is built against 2.6.9
headers).
