Have you seen Larry Barello's AVRX real-time kernel? It includes message 
queues, as well as tasking, semaphores, timers, and single step debug 


He has a version for GCC. I haven't used it, but he's an active member of 
several lists (including this one), and has his own list for support of AVRX.

I don't know whether the message queue code itself can be easily separated 
from the tasking code.

There is another free RTOS at: http://www.drtak.org/develops/RTK , but it 
doesn't provide message queues like AVRX does.

Also, there's an open-source AVR CAN project at
but it seems to be in assembler. I think they're bit-banging the CAN.
