a hello, and a few gcc v4+ implementation questions

[Mayuresh Kathe]

Hello, I've just joined the list as I've returned to the GNU world after
almost 9 years.
Feels good to be back. :)

I've been reading up on GCC through various articles online and have
come to understand that GCC now is being written using C++.
Would I be correct in my assumption that the older (1998 with 2003 enh)
C++ standard is being used? or is it the brand new C++11 (which seems
highly improbable).

Thanks and Regards,
