"Is is still the best C compiler"

What do you like best?

I have been using the Watcom compiler for more than 20 years. It is ANSI compliant and a decent IDE. I would choose an alternative if I were starting fresh, but it still accomplishes what I need it to do.

What do you dislike?

I am afraid that it is falling off the curve. I would like an IDE as good as Eclipse and a realistic 64-bit solution. An alternative would be to make the compiler compatible with Eclipse.

Recommendations to others considering the product

Not a place to start if you have alternatives.

What business problems are you solving with the product? What benefits have you realized?

Big data analytics. It is an essential everyday tool for handling the gigantic databases I use. I frequently analyze datasets with 100 million or more records, and native code is the only real solution.
