Yes, and they didn't really create any conflicts that didn't already exist.
No one thinking broadly enough would define "bool" because of the high chance
that somebody else did too, because it's such an obvious name. The same is
true of names such as "int32".
For this reason, before C99, there were few software distributions that
defined "bool", with the chance of a distribution doing so inversely
proportional to how popular the distribution was.
Likewise, programmers who defined "bool" in their own private code were (and I
guess still are) largely the inexperienced ones -- who hadn't yet been bitten
by an interface header file that arrogantly claimed the name "bool."
