I'd kindof always dismissed Ada because it was so slow in the past and 
the need for an installed Ada front-end.

Note the "slow" was back in the mid 90s last time I looked at it :-0  I 
haven't compared it to GCJ or anything like that, but that's certainly 
easily accomplished.

At least for Linux systems, the bootstrapping problem is largely a 
solved problem by the major vendors.

Let me run some tests, this may be a better alternative.
