If you use jikes as a compiler, using ant or not, you'll more than probably
have the same behaviour :)
Now, if you use javac as a compiler and use the optional "depend" task of
ant to do the dependencies check, it is very likely that you will get the
same thing too.

I don't know if in ant1.3, the depend task will still display the time it
takes to perform the check, but it was indeed a real good idea to determine,
depending of the size of your project, if a complete rebuild wasn't better.
Maybe this could remain in verbose or higher mode ?
