Comment(by nickm):
>presumably sufficiently old gccs don't have those extensions, and they're
useful enough that some non-gcc compiler might implement compatible ones -
either now without my being aware of it, or in the future.
They were introduced in gcc 2.0, which was released in 1992 -- we will
never want to build with a GCC that old, I think. (I tried to bootstrap
gcc 2.0 for the fun of it, but it doesn't even build cleanly any more.)
There are also compilers that support this extension: notably, clang and
(I believe) icc. But they both define __GNUC__ to indicate that they
support the usual GCC extensions.
I'll consider the other points when I'm more awake, but I wanted to
braindump the above stuff before I forgot it.
