There are several further problems in the AVR32 tree. All of them just
exist in trunk. See my last mail on the list. (Nut/OS Build Problems for

Not a big problem, either? Do you fix it? (Sorry, I don't know the
setting for the at91sam7se-ek and further boards.

It fails? No problem here... Which platform did you use?

I further fixed several other small problems, I found in the meantime.
Especially a very strange problem in the at91_emac, which was introduced
by using the phy driver.
The emac_reset() has a timeout parameter, which was not used in this
function any more as the Phy Driver was introduced. But the tmo variable
was still used as parameter to a debug print, which for sure was
replaced by "nothing" during a normal build. The result was a stack
overwrite on function return. I think that's a compiler bug, who does
not recognise that the parameter is not used.
If you (and all others too) could do further testing of the branch on
real hardware would be very appreciated.
