Early this year we have ported RTEMS (MPC860 target) to MetroWerks 
CodeWarrior for Windows. There was a significant difference in size too. 
The 2 main reasons are: 
* CodeWarrior uses *real* EABI, not just some #defines in the Makefiles  
* The Linker does a real good job of dead-stripping code  

And this had nothing to do with the C-Libraries, because we have used NewLib 
for our port. 

In case you are interested, we could go into more details.
