I will try also with this version of WinAVR later. (I'll let you know)
Maybe the problem has also to do with the fact, that this line ends up in a
library,
which is linked together with other libraries at the end?

Well, that's intersting.
It does not.
Just by linking the library with the offending line, you get errors in other
files,
which, if you don't link this specific library are compiling and even
executing fine.

This is the real linker output, but dont be confused by the errors in
various files and even precompiled libraries.

If I just add, or remove a character of the string like:

const char      max7219_C_VER[]__attribute__((__progmem__, __aligned__(1)))=
"@(#) $Id: max7219.c,v 0.0 2004/01/25 18:58:09Dafni Exp $$";

Everything works fine:

---- link executable -----
avr-gcc  -TF:/projects/undercvs/bergomat/config/atmega128_341.x  -Wl,-Map=ma
x7219_test.elf.map,--cref -mmcu=atmega128 -o

Isn't this a very interesting error?
