  That was my first thought too, but note:

>> ./xgcc -B./ -B/usr/local/arm-elf/bin/ -isystem /usr/local/arm-elf/include

  I would expect it to have been found.  Oliver, some other things to check
are:

- did "make install" for binutils run correctly and to completion?
- did you use the exact same prefix for configuring binutils and gcc/newlib?  


    cheers,
