how to run pingpong?

Hi all!
I've two problems and i hope you could help me.
My goal is to compile and run l4 for mips64 on qemu.
I'm currently stuck because of compilation errors. The first error was
because mcpu was not a valid option. I changed it in the makefile to march
(thanks to l4:hackers) but now there are syntax errors when i compile. They
look like that :

This two warnings are repeated a lot of times, and after

Because of the errors i tried to run it on x86 architecture. I ran the
demodisk available on the site but when its launched  i don't know how to
run pingpong. In fact I think I always stay in kdb. At the beginning i can
choose and test ipc and after I'm a bit lost. I would be cool if someone can
help ;e.
Thanks.
