`-Os'
     Optimize for size.  `-Os' enables all `-O2' optimizations that do
     not typically increase code size.  It also performs further
     optimizations designed to reduce code size.

     If you use multiple `-O' options, with or without level numbers,
     the last such option is the one that is effective.
