This is more than a bit misleading. In order to compare equivalent C, C++ and Ada compilation times, you have to add the time it takes to run a "make depend" and "lint" on the C/C++ code, since the Ada compiler is of course performing that functionality. Also, of course optimal recompilation technologies would preclude the need for many/most recompilations in situations like this. -- Bob Kitzberger +1 (916) 274-3075 rlk@rational.com Rational Software Corp., 10565 Brunswick Rd. #11, Grass Valley, CA 95945
