You can use ccache to speed it up if you want to compile it over and  
over again.  You can use -O0, that's faster than -O2.  Also, you can  
install the new compiler, and then just use make instead of make  
bootstrap, that's also faster.  Plus, you could just use make all  
instead, that's faster than bootstrap.  And lastly, leaving out the - 
g is also faster.
