Oh, yeah, almost forgot:

`-fno-rtti'
     Disable generation of the information used by C++ runtime type
     identification features (`dynamic_cast' and `typeid').  If you
     don't use those parts of the language (or exception handling,
     which uses `dynamic_cast' internally), you can save some space by
     using this flag.

This is one that comes to mind, there should be others, too.
Try 'info gcc'.
