This shows the two different points of view: for a GCC developer this is
the most relevant data when tracking down memory usage; for a GCC user,
the resources consumed on the system are of premier interest.

I can happily report that today was the first day where I managed to
compile the application behind PR8361 with -O3 without badly affecting 
interactive use on my workstation; that is, your improvements are really
user visible!
