He is right.  GCC is notoriously organized in front-ends, which translate 
any given programming language into an intermediate language which is 
supported by GCC (it appears to support at least 3 intermediate languages), 
and back-ends, which translate code written in those intermediate languages 
into machine code for a specific target platform. 

This approach may appear an "unnecessary complication" at first.  Yet, this 
approach means, at least in theory, that you only need to write a new GCC 
front-end in order to get your new programming language to be supported in 
every platform supported by GCC, and it also means that you only need to 
write a new GCC back-end in order to offer support for each and every 
programming language supported by GCC in a brand new target architecture.

Also, by relying on an intermediate implementation it is also possible to 
perform all sorts of code optimization on a single piece of data and yet 
reap benefits from that optimization when writing code in any programming 
language supported by GCC and when targetting any platform supported by GCC.

Hope this helps,
Rui Maciel
