GCC 4.0 vs. 3.5 -- don't decide now!

I have no quibble with everything you said except this:

Don't perpetuate this pernicious error.  Version numbers are not
decimal fractions.  They are 3-tuples of nonnegative integers,
expressed in a convenient shorthand.  There is no special meaning to a
.5 or a .90 or even a .99 release.

Would you say that (3 5 0) was halfway to (4 0 0) ?
