Re: [avr-chat] binutils, gcc and avr-libc versions

[Ing. Daniel Rozsnyó]

Hi,
  don't be surprised. Upgrading the toolchain breaks things seriously. 
Once I've tried to do so I ended up with unimaginable problems which 
were hard to track down. When I found out what the issue was, I decided 
not to upgrade.

  The change between avr lib versions was that they changed the order 
of arguments in eeprom access functions, so the source and destination 
became swapped.

  Crazyness.

  Regarding to your const issue - try to fix your sources with a 
script. I had to do that in PHP when they replaced ereg with preg and 
the syntax was a little different.
