We use codesourcery toolchain arm-2010.09. The rootfs was built using PTXdist.
I think, but have to verify, that NPTL is used as threading library.

I don't know, but will find out.

In the example I gave, no floats were used. Does Xenomai needs to support iwmmxt
floats also in this case? And would compiling the application with -msoft-float
do the trick?

ATM, I'm busy with other things but have time to investigate tomorrow evening.
