Looks ok. Well it did in your html email.

Have you cut off some of the output ?

The output I posted was for the SPARC architecture and not the AVR so 
this will be different. Also I used the 4.11 tools and not the 4.10 
tools. They are different.

RTEMS 4.10 is the current released version and is termed "stable". We 
only add bug fixes to this version and the tools do not change unless 
there is a bug fix we think is important.

RTEMS 4.11 is the development version. This is always changing. It can 
be unstable and contain bugs. We add new features here. The tools are 
also newer and for this reason the tool details may vary.

If you wish to verify your set up I suggest you download the sparc 
architecture tools and execute the same commands I did.
