            - The IDE was updated to use gcc version 4.4.; we no longer ship versions 2.95.3 
               or 3.3.5. For more information about the enhancements, see 
               http://gcc.gnu.org/gcc-4.4/changes.html. 
            
 
            - The IDE uses GDB 6.7.
 
            - To be consistent with other platforms, the -n option for the 
               cp command was renamed to be -u. The -n 
               option is still recognized.
            
 
            - The low-level atomicity GCC functions were updated so that they no longer use spinlocks, 
               which failed under certain circumstances.
            
 
            - The default for Tab completion in ksh is now complete-list, 
               which will list possible choices if the completion doesn't complete. To get the old behavior, 
               add a line with bind ^i=complete to your ~/.kshrc file.
