Re: [avr-gcc-list] $DATA_ORIGIN in binutils-2.18

[Ruud Vlaming]

OK, i understand now what the problem was.
If you first apply the data-origin patch, this all
works well. However, that patch was not included
in the original script in avr-freaks.
  build-avr-gcc-4.2.2-libc-1.6.2-makeinfo-fixed.tar.gz
Well whatever ...

greetings
Ruud.
