As Andrew pointed out, you just need to type "make" (or "make install") 
to do a build with your changes. Also, you can skip the "make bootstrap" 
when doing a complete build. This is only really necessary when building 
with a questionable CC or testing the compiler for mis-compilation bugs.
One handy feature when working on the compiler is that if you " cd gcc" 
in your build directory before typing "make", it will automatically 
rebuild the files you are working on without optimization, making them 
easier to debug.
