It seems very odd to me that the author would choose to add such an FAQ entry but fail to explain /how/ or /why/ GCC "is a crap." I'm sure there are several valid criticisms of GCC, but to be so forward without a list of examples or even a link to someone else's article does not inspire me to trust your software in my ring 0.
As someone's personal hobby project - more power to that person! It takes a lot more skill and dedication than I possess. I wish nothing but success and good fortune. And you can be as opinionated as you want.
As something to be presented to the wider world, with a desire to have (testing) users and contributions... Hmm.
You left out "In the spirit of lighthearted development" and "As the project matures, implementing a comprehensive suite of automated tests is definitely on our roadmap."
Right! Even though that post is almost 20(!!) years old, Theo is respected enough that you could use that as a rationale for crapping on GCC.
Obviously Theo has his detractors, rightfully so. And the language he uses in that post is not what I would use at all. It's downright unacceptable. But at least it's something - a thing from an authority you can point to and say "this is why!"
