Found it. It lies in my linker script.
Target cpu is ATTiny13
Under the 'old' toolchain [binutils 2.19] the script needs to have
"OUTPUT_ARCH(avr:3)".
Why? - I don't know. I hadn't noticed this until now. If I 'correct' it,
it complains:

ld: avr:3 architecture of input file `crttn13.o' is incompatible with
avr:25 output.

Where does it get arch3 from ??

The new toolchain requires "OUTPUT_ARCH(avr:25)" which seems correct.
So I have a solution (I will make a complete fork of all projects when I
have completed testing the new toolchain) - thank you Jörg. :-)

In your patch from FreeBSD, marked for GCC 4.3.4:
--- ./gcc/config/avr/avr.c~     2010-03-05 17:16:20.000000000 +0100
+++ ./gcc/config/avr/avr.c      2010-03-05 17:19:30.000000000 +0100

Whereas the gcc 4.3.4 tarball has it's "gcc/config/avr/avr.c" at 15.06.2008

Running "patch < patch-gcc" in the top directory gives:

Perhaps you should have used the -p or --strip option?

Looking in the avr.c.rej file:

The text /*3-Byte...... is not in the file to patch, so it dumps.

This file looks quite old, I wonder if the gcc-4.3.4 tarball is correct?
