Dear Professor Olowofoyeku; I have compiled some C++ codes quite similar to the timing test program of the NTL Library, and they have given too some erroneous results. I am going to write and compile some others, see the facts, and after putting them in a strict formal manner, I will send them to the MinGW developers and here. Perhaps, perhaps, there may be a missed "link command option" which must be added during the compile time. Whatever, MinGW is a true wonderful collection provided very generously to us. Really thanks a lot to its smart and laborious developers. I use it along with the GNU Tools Suite; being able to get those wonders on Windows platform, open sourced and free, what gift... Sincerely Yours, With my best regards. Kadir T. Yuce --------------------------------- Ne gardez plus qu'une seule adresse mail ! Copiez vos mails vers Yahoo! Mail
