I am using WinAVR-20050214 (avr-libc 1.2.3) and get the following
warning 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>
I searched avr-libc bugs, tasks, and patches (I have been getting
connection refused errors trying to access the mailing list archives
for a day or more) and haven't found anything related to this issue.
I can easily work around it by commenting out the definition of GIMSK
in <iom8.h>, but I figure someone else will encounter this as well and
it should be fixed in the appropriate manner (I don't know what that
is).
