RE: OS Ports of GCC/G++

[Witness <bm_Witness at yahoo dot com>]

Thanks. I think that covers all my questions about it.

As far as what your question, it's kind of both. We want the first system to 
use a lot of the features of the final system, but on a limited basis because 
of its purpose. However, we want the first system to utilize the GCC/G++ 
compiler.

Thanks a lot.
