Using the OSKit POSIX Thread Library

[Tiago Jorge]

Continuing the goal to port my aplication to an L4 server, i'm trying to 
use the OSKit lib to POSIX threads.
I'm using c++ and building in l4env_freebsd mode. First of all, the 
static link to the lib wasn't in the modes.inc file. I've included it 
there. I've tried to build my test project, that simply starts a thread. 
The test files compiles but it doesn't do the static link. The error is 
the following:

I presume one of two cases:

- My code is wrong somehow, but i've tried to build the oskit example os 
the philosophers dinner and didn't worked as well
- There is no support for POSIX threads in your version of OSKit :(

thanks in advance
