[gccsdk] Any chance of a newer GCC version than 4.7.4?

Hi all.

I'm new to this list, and apologies if this has been asked before (I checked the archive). I notice that the current version of GCC for RISC OS, while built relatively recently, is based on a version of GCC from 2014 (https://gcc.gnu.org/releases.html).

Is there any reason why we're basing it on such an old version, and is there any chance of getting a later one, preferably based on the latest GCC version?

I'm developing C++ applications, and a lot has changed since 2014, and even then, the GCC version only included a partial implementation of C++11. Thus, we're missing several major revisions of the C++ standard: C++11, C++14, C++17 and C++20
