Could try it.  It's just a warning, and only in compiling the library,
so we could leave it.  (You have to edit gcc.opt anyway since some of
the new switches aren't supported by older GCC).

And I looked at this for a few minutes - and it looks like a gcc
bug.  It works with __extension__ in other contexts during compiling,
but for some reason it just won't take this one.  #defining it away
makes it compile.

It does support them, so it's just a matter of deciding what to do - but
I'm busy this week.  When I get a chance.
