Why not raise the minimum gcc compiler version even higher?

The latest GCC 5 release is only three and a half years old.

You argue slightly against yourself here.

I don't?

Yes, it's mostly a question of practicality vs latest.

clang requires a _very_ recent version.
gcc _could_ require a later version.
Perhaps 8 might be best as that has a __diag warning control mechanism.

I have no idea what you mean?

gcc 8.1 is now 3 years old today.

And there will be a new GCC 8 release very soon now!

The point is, you inconvenience users if you require a compiler version
they do not already have.  Five years might be fine, but three years is
not.


Segher

Users & especially devs should upgrade then. 3 years of not updating 
your compiler - if you regularly build the kernel - seems nonsensical.
