We all know better, but how tiny is the fraction of C programmers who
have ever even *seen* the ANSI C spec, much less know in detail what
it says?
OK, but to me "knows C" (the predicate in my statement) certainly
means being familiar with the standard, not necessarily by reading it,
I am sure there are lots of good books on C that have a good account
of the rules (K&R is clear enough on this particular issue).
