Okay, let's forget about restrict.  It's not that important.  I just
thought it could be easily ignored by compilers, but it's not very
useful itself.

Hmmmm, C99's extern inline is one I'm very interested in.  Would you
mind pointing at the changes in 4.x you're referring to?  I'd like to
learn about them.

Even if we can't rely on it now, I'd like to be able to rely on it in
the future (maybe 10 years from now?).


Have a lovely day!
