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.
