Details:

Signature bytes are usefull for bootloader implementation.

They are supplied with the Atmel assembler include files but none of the C
compilers header files I have looked at have them.

Example of existing signature bytes info in assembler .inc files:

; ***** SPECIFY DEVICE *************************************************** 
.device ATmega164P 
#pragma AVRPART ADMIN PART_NAME ATmega164P 
.equ   SIGNATURE_000   = 0x1e 
.equ   SIGNATURE_001   = 0x94 
.equ   SIGNATURE_002   = 0x0a 

#pragma AVRPART CORE CORE_VERSION V2E
