Yes you can.

You can either use the linux synthetic target, which behaves like a real 
target, but isn't quite as accurate as a proper simulator. That runs from 
a shell/xterm.

Or you can use the proper PC target, which you can boot off a floppy or 
IDE disk (although I think the patches to do this are still outstanding). 
Or you can even boot using GRUB - the GNU boot loader.

Some people have reported success with STL, although no official port yet 
exists. There are ways to add this _fairly_ simply.

Exceptions and RTTI always add overhead everywhere if they're enabled, 
even if they're only used in a small part of the code.

Support for this is to be added "soon". It has in fact been done, but has 
not been done on all platforms, and therefore hasn't been checked in yet.
