You can try compiling your units with -Ur, which will tell the  
compiler that it should try not to recompile those units. That won't  
help if the CRC of a unit they depend on has changed though. The  
reason is that a changed CRC means that something in the interface of  
that other unit has changed, which in turn may have an effect on the  
current unit (it may call routines that no longer exist, use constants  
whose value has changed, override methods that are now located in a  
different VMT slot, etc).
