Can you check if GCC 4.6.1 still needs these patches (other than the
soft-float patch) and other fun changes? I don't think it does.
For a 4.6.1 softfloat patch, see [1] (I'm not sure that the 4.6.0
softfloat patch will apply cleanly to 4.6.1).

Using binutils-1.22 and gcc-4.6.1 with the above patch does build gcc
cleanly. However, uClibc-0.9.32 fails now with:

BTW the target HW again is http://www.andahammer.com/mini2440-sdk/
Toolchains are fun ;)
Yeah but I'm ready to be reading different chapters now. :)
