What if you are porting code to a non jvm... if you copy and paste
something and it has no free, you're screwed.
i.e. say you have some JVM algorithms that now need to be used in win32 or
bsd using the regular fpc compilation.... can't port them without
inspecting the code carefully for missing free's
