Details:

Using WinAVR-20050214 (avr-libc 1.2.3) the following warning occurs when
compiling for the ATmega8 MCU:

c:/winavr/avr/include/avr/interrupt.h:117:1: warning: "__EICR" redefined
c:/winavr/avr/include/avr/interrupt.h:114:1: warning: this is the
location of the previous definition

I believe this is because <iom8.h> defines:
<snip>
#define GIMSK   _SFR_IO8(0x3B)
#define GICR    _SFR_IO8(0x3B)   /* Changed in 2486H-AVR-09/02 */
</snip>

And <interrupt.h> assumes that only one of these is defined:
<snip>
/* Define common register definition if available. */
#if defined(EIMSK)
#define __EICR  EIMSK
#endif
#if defined(GIMSK)
#define __EICR  GIMSK
#endif
#if defined(GICR)
#define __EICR  GICR
#endif
</snip>
