Requirement is probably an overstatement. (Score 1)

I am also a student at UKY, while CodeWarrior is recommended by the instructor and TAs, it was made perfectly clear to me that HP-UX accounts with gcc/g++ would be available for anyone who wished to use them. With introductory classes with ~300 students, I think it is a smart move recommending a windows development environment, considering a majority of students have probably never used a unix system.
