What licence(s) does GNAT and the runtime fall under now?

[Luke A. Guest]

Hi,

I was just wondering what licences are used for GNAT now that AdaCore
has GNAT-GPL rather than GNAT with GMGPL'd runtime.

It seems that the source - when I last looked - for the runtime was GPL
rather that GMGPL, but I thought that only the FSF could change the
licence of these files?

Can somebody please explain what licences are used for GCC-4.3.x & GNAT?

Thanks,
Luke.
