I'm a beginner. I'm using an atmega8L with 12MHz. when I compile the code (WINAVR) , it does not recognize the register x4 in usbdrvasm12.S
The error messages I get are,

Code: 

Assembling: usbdrvasm.S
avr-gcc -c -mmcu=atmega8 -I. -x assembler-with-cpp -Wa,-adhlns=usbdrvasm.lst,-gstabs  usbdrvasm.S -o usbdrvasm.o

usbdrvasm12.inc:387: Error: register name or number from 0 to 31 required
make.exe: *** [usbdrvasm.o] Error 1


The first error points to the code,

Code: 

subi    x4, 1               


I would be grateful if anyone can help me to solve this out.

Thanx..
