Hello Sebastian,

Jesus, its true! My last patch that should place constant data into the data section
doesn't work as expected. If string constants are used in the code, they are placed
in the data section, but the generated code adresses them in the text section,
leading to the errors that you described. I have restored the old version of the patch,
please download this version from http://www.home.at/~eauth/uclinux/. Thank
you very much for the hint.
