@Jonathan

I still think that the messages of Comeau and Clang are better than GCC's. I
will try for 4.7 to produce a patch to change the message to be like:

error: default initialization of const object 'g_d' requires a user-provided
default constructor [-fpermissive]
note: 'const class D' has no user-provided default constructor

Do you agree? 

(I'd like to keep the note to jump to the declaration of class D).

@Piotr,Ryan

I started a list of GCC diagnostics in the wiki. 

http://gcc.gnu.org/wiki/VerboseDiagnostics

There is only one but the idea would be to collect in a single place extended
explanations and fix-it hints about gcc diagnostics. Perhaps in the future such
knowledge can be added to the compiler proper and enabled with a
-fdiagnostics-explain or -fdiagnostics-fix-it. 

I think this could be a killer-feature for GCC to have, but collecting the data
is a lot of work for a single person. This is a way to contribute to GCC
without writing a single line of code!
