First of all I think you mean gnu-c here (or you can just
say c in this context if you like), gcc is the GNU compiler
collection, and includes all three of these languages as
well as many others.

Second, if the gnu-c code runs 2-3 times as fast as the
C code it is simply NOT the same code. Usually when we look at
examples like this in detail, we discover that what
people think are "identical" programs are in fact totally
different and apples and oranges are being compared (*)

An odd phrase, what's so wrong about comparing oranges on
apples. I think I prefer oranges in general :-) :
