[avr-gcc-list] Customizing interrupt vector entries when using GCC?

[Rick Mann]

I'm working on an ATmega128, using avr-gcc, and I need to speed up  
the handling of interrupts on three pins INT5, INT6 and INT7. Rather  
than creating three interrupt handlers that all call a single unified  
handler, I'd like to put the same handler in each of those three  
slots in the vector.

I suspect to do this I'll need to make a copy of the .S file that  
represents the runtime glue. Can someone explain to me how to do  
this, and how to adjust my makefile to build it properly? I'm not  
familiar enough with gcc.

Thank you.
