Hi Dave,

Good idea and I do so for tree compiler still install:
gcc-3.0 -E

struct atapi_mechstat_header {

        __u8 fault : 1;
        __u8 changer_state : 2;
        __u8 curslot : 5;
# 427 "ide-cd.h"
        __u8 mech_state : 3;
        __u8 door_open : 1;
        __u8 reserved1 : 4;
# 438 "ide-cd.h" 
        byte curlba[3];
        byte nslots;
        __u8 short slot_tablelen;
};

gcc-3.2 -E

struct atapi_mechstat_header {

        __u8 fault : 1;
        __u8 changer_state : 2;
        __u8 curslot : 5;
# 427 "ide-cd.h"
        __u8 mech_state : 3;
        __u8 door_open : 1;
        __u8 reserved1 : 4;
# 438 "ide-cd.h"
        byte curlba[3];
        byte nslots;
        __u8 short slot_tablelen;
};

gcc-3.3 -E

struct atapi_mechstat_header {

        __u8 fault : 1;
        __u8 changer_state : 2;
        __u8 curslot : 5;
# 427 "ide-cd.h"
        __u8 mech_state : 3;
        __u8 door_open : 1;
        __u8 reserved1 : 4;
# 438 "ide-cd.h"
        byte curlba[3];
        byte nslots;
        __u8 short slot_tablelen;
};

Do you notice any difference OTC above I encounter another use of slot_ta=
blelen
as:

struct cdrom_mechstat_header {

        __u8 fault : 1;
        __u8 changer_state : 2;
        __u8 curslot : 5;
        __u8 mech_state : 3;
        __u8 door_open : 1;
        __u8 reserved1 : 4;
# 927 "/usr/src/linux-2.4.20-pa21/include/linux/cdrom.h"
        __u8 curlba[3];
        __u8 nslots;
        __u16 slot_tablelen;
};

hmm could this be a typo at one moment "unsigned short" would be changed
"__u8 short" ???

More over what could be the actual patch:
__u8 slot_tablelen;

or as in the 2d structure

__u16 slot_tablelen;

Cheers,
    Joel
