Making the kernel strictly conforming is a ship that sailed long ago,
for several reasons. Anyway, supporting several compilers and other
tools, regardless of extensions, is valuable.

No, we aren't particularly tied to `gnu89` or anything like that. We
could actually go for `gnu11` already, since the minimum GCC and Clang
support it. Even if a bit of code needs fixing, that shouldn't be a
problem if someone puts the work.

In other words, the kernel code is not frozen, nor are the features it
uses from compilers. They do, in fact, change from time to time.

You're welcome! There are quite a few new attributes coming, mostly
following C++ ones.

Not sure what you mean. The standard does not evolve through
implementations' agreement (although standardizing existing practice
is one of the best arguments to back a change).

Cheers,
Miguel
