Summary:  Fuse mask in boot.h wrong?

Original Submission:  Fuse-Mask in boot.h may be wrong. In current (31 Mar 04):

/* Define the bit positions of the Boot Lock Bits. */
#define BLB12           5
#define BLB11           4
#define BLB02           3
#define BLB01           2
#define __BOOT_LOCK_BITS_MASK  (_BV(BLB01) | _BV(BLB02) 
                               | _BV(BLB11) | BV(BLB12))

didn't work for me in an AVRStuido STK500-plugin-compatible bootloader on an 
ATmega16. To fix this issue here it has been changed like this:

/* Define the bit positions of the Boot Lock Bits. */
#define BLB12           5
#define BLB11           4
#define BLB02           3
#define BLB01           2
// mt:
#define LB2             1
#define LB1             0
#define LOCK6           6
#define LOCK7           7
#define __BOOT_LOCK_BITS_MASK (_BV(LB1) | _BV(LB2) |  
                               _BV(LOCK6) | _BV(LOCK7))

BTW. The bug I've submited regarding sleep.h and ATmega169 haven't been fixed 
so far. At least a remark in the documentation (like the one in/for eeprom.h) 
would avoid time-consuming debugging on the users-side until someone has time 
to fix this bug.
