Ah, OK... So you mean if NeXT hadn't based their 1980s effort on GCC, i.e. if there had been a decent BSD-licensed C compiler back then.

It's worth mentioning that this was a long time ago, before a fair number of HN readers were born, and also at a time when GPL vs. BSD licensing likely wasn't as much of a topic as today. Comparing GCC with Clang when we're talking about things that happened in 1988[1] just doesn't seem to make any sense to me.

[1] Per Wikipedia's article on Objective-C, the year that NeXT's GCC changes happened.
