Hi Ralf,

     Is the version of development tools for RTEMS-4.10 finalized ?  It 
seems that I am not the only one
who might have problems with the development tools.  The code in RTEMS 
4.10.2 O.S. should function
properly as well even though  it is a little bit different from the 
patch I applied on RTEMS 4.10.0.
However, the compiled code proved otherwise.

    IIRC, I used the pre-built development tools for RTEMS 4.10.0.  
Thus, I should not confirm which version
of tools and patches were applied. When I downloaded RTEMS 4.10.1 and 
RTEMS 4.10.2, there were problems
with the pre-built one on the Ubutu PC that I had to build the tools 
from the source and used whatever patches
was posted along with 4.10.1 and 4.10.2.

   So far, my patched code for RTEMS4.10.0 works well with the prebuilt 
tool which was released along with
4.10.0.  Did anyone succeed with the current 4.10.2 development tools on 
PowerPC ? I haven't updated the
tools for a while, but Robert might have difficulties with the recent 
one, too. I hope that those information
helps to move RTEMS-4.10.2 forward.
