Details:


In avr-gcc.exe (WinAVR 20081205) 4.3.2,
the ATTiny88 CTC0 has wrong value in iotn88.h

iotn88.h currently has:

#define TCCR0A _SFR_IO8(0x25)
#define CS00 0
#define CS01 1
#define CS02 2
#define CTC0 7

per the data sheet CTC0 should be 3.

The value of 7 causes unexpected/undocumented
mode of operation.

AVRStudio 4.15 Build 623 XML file has correct mask of 0x08.
