Okay, that makes sense. Actually, 'gnat' is mentioned only in passing --
it is not meant to be an Ada book :)

Okay okay, I stand corrected. Care to try a rewrite then?
Compilation of Objective-C programs is done with the same
driver that is used for C code. This eliminates the need
for an intermediate C version, and allows for better object
code and better debugging capabilities.
Patches welcome :)
And I take note of Colin Howell's comments -- if this paragraph needn't
be paralleled to the the G++ one, that's fine. The bigger point was just
that of the three languages discussed at any length in the text, two of
the three got a writeup in chapter 1, but Objective-C didn't. I took a
guess, copying wildly and not knowing what exactly should be said. If
anyone knows more Objective-C -- like say someone at Apple -- feel free to
offer something more appropriate about GCC and the language.
