This question was a genuine inquiry for me when I was studying programming in C and considering switching to Clang which appeared to me more user friendly and more newbie friendly than GCC. I did in fact switch to Clang, since then based on the answers I received.
I suspect that the linked page is now only visible to users with very high reputation and moderators. I still think the info provided is very useful to anybody starting with C programming and was dismayed at it's closing and really surprised by it's deletion. The very positive upvotes the question and the answers provided (65 upvotes for the question and 48 upvotes for the accepted answer, 18 for the second answer etc. for those that can't see the question ...) should give a hint that people found it useful. Even if some people think it is not a perfect fit within Stackoverflow (I still disagree even with that) why not just leave it closed but not delete it.
Addendum: Thanks to jmort253, the question has been edited to reflect the issue I was having during my C programming course. I am willing to edit the question further, but while I can see the question, I am unable to edit it myself (the edit button is still greyed out), in an effort to have the question undeleted (and hopefully later re-opening it).
