It isn't. I'm pretty sure you are comparing different compileres, i.e. your "gcc" might be pgcc, while your "g++" might be gcc-2.7.2 or sth. else. (Have you compiled it yourself or installed both packages?). > I also had the feeling that the pgcc compiler generates larger > code than gcc-2.7.2. Is that all because of the optimization? Yes. Given some compiler switches, you should be able to get smaller programs then 2.7.2 (-m486) as well. (try -O2 -Os). -----==- | ----==-- _ | ---==---(_)__ __ ____ __ Marc Lehmann +-- --==---/ / _ \/ // /\ \/ / pcg AT goof DOT com |e| -=====/_/_//_/\_,_/ /_/\_\ --+ The choice of a GNU generation | |
