Be careful when making statements like this! ;-) If you are talking about
strictly automatics (locals), this is true, but not if you are comparing
automatics and external (global) variables. Automatics can be much more
easily and effectively optimized than externals; witness the code generated
by the GNU C/C++ compiler.
