[Icc-avr] #define problem

[Michael Dipperstein]

Why not just:

#define ATMega8

#if defined ATMega8
#include <iom8v.h>
#endif

In fact the Makefile generated by the IDE should put something like 
-DATMega8 in the parameters passed to the compiler for you.

I've done things like this before:
#if defined ATMega88
#include <iom88v.h>
#elif defined ATMega48
#include <iom48v.h>
#elif defined ATMega168
#include <iom168v.h>
#elif defined ATMega8
#include <iom8v.h>
#endif

Hi,

    Is there a way to do

#define MEGATYPE  "Mega8"

#if (MEGATYPE == "Mega8")
  #include "iom8v.h"
#endif

Thanks for your time
Sylvain Bissonnette
