--- Comment #9 from Rich Felker <bugdal at aerifal dot cx> ---
I don't know what the maintenance policy is for non-latest releases, but it
would be wonderful if we could get these into the 4.7 series before it's
closed, too. Bootstrapping new toolchains/systems with a different libc than
the host system's libc, it's much easier to start with a GCC that doesn't need
C++, and it would be a big help if our users could just start with GCC 4.7.x
and have it work out of the box, rather than needing to apply third-party
patches.

(Speaking from the standpoint of musl maintainer.)
