I don't think so Manny, see <http://www.oddchange.com/gcc6809/> for its 
current status.  From that page, to download, you'll need a working SVN 
client.  Apparently its working pretty well with gcc-3.4.6, but not as well 
with the gcc-4.1.  From that web page, its a one man project unless someone 
with compiler writing knowledge were to offer to help.  Its been over a 
decade since I last fooled with c.prep.  I don't think that would make 
me "qualified" to muck around in the internals. :)

I have little actual knowledge, but would assume that gcc-3.4-compat (or 
similarly named packages) would have to be installed on a linux box, as all 
recent distros are now shipping a gcc-4.1 variant, which makes better code, 
but is also a bit slower.

We have a linux utility called ccache that can speed that up, it caches 
compiler output modules, and if the checksum of the individual src file has 
not changed, then on subsequent passes to rebuild the same module, it 
intercepts the compiler calls and pulls the object back out of the cache.  
For building kernels, that can cut a 20+ minute compile time down to 3 or 4, 
which is rather handy.

If running gcc6809 is slow, you might consider installing ccache too.  But its 
little or no help when building something new that it has not seen before.
