Which is why --prefix=/usr/local is there - most system compilers
go into /usr, scattering assorted detritus thereunder. The default
configuration shown here (that is, --prefix=/usr/local) doesn't 
stomp on the system compiler.

I've built GCC more times the last year than I care to count, and I have
yet to blow up my system compiler.
