It's not so much wanting to run it on the device (though that would be 
fun just for the hack value). I was just saying that it adds an annoying 
step to building using JHC, since you have to run JHC on the host, and 
then gcc inside the scratchbox. It's not a limitation, just makes it 
hard to write a working Makefile.

I was just playing around with it, so that never mattered much. I 
suppose one could have two Makefiles in a proper project.
