Not to niggle, but there was a particularly odd post at https://stackoverflow.com/questions/7207766/what-c-compiler-when-building-eclipse/7207787#7207787
The original answer was "gcc ofcourse, it is the best."
The poster made the unsubstantiated claim "Because,gcc comes for free(open source), it is open source and it is much better than the buggy msvc.", and I think a comment like that (in particular the line 'better than the buggy msvc') was unsubstantiated.
It wasn't clear, based on the choices, how to properly flag the remark. How does one indicate that a post had a particularly strong opinion or made an unsubstantiated claim?
