GCC

Ever since I started programming, I loved compilers with IDEs. I never thought I could do without those syntax checkers. However, I hated trying to write GUI applications in Pascal or C. But, now, I have started using gcc, GNU's compiler collection. Despite all my fears and hopes about it, one of which was a lack of an IDE-syntax checker environment, I love using gcc. I find it very easy to work with and extremely flexible and efficient. I don't need any fancy procedures for GUI-related things. It has helped me get fairly good at C, although I am still generally a beginner.
