Do the warnings show up because you aren't HANDLING exceptions or  
does the compiler throw a warning when it encounters an exception  
message that it ignores because of the no-exception flag?  If the  
case is that you're not handling them, then what about if you HANDLED  
them in your code (which seems like a decent bug-checking technique  
in general), and then for release builds just use the no-exception  
flag and it sounds like it'll ignore compiling all of the exception  
code anyway?

Also, was your version of Ogre compiled with exceptions turned off?   
I'm not an expert on C++ exceptions (probably obvious by now), but it  
seems logical to me that if you used the no-exception flag then the  
compiler should ignore any warnings generated because of exception- 
based code, and if the libraries for the Ogre engine were built  
without it, then they wouldn't generate any exception-based  
warnings.  Is this wrong?  (If so, I apologize for the wasted time,  
but it's useful to learn, right?)
