This is pure curiosity: is an example of these flaws the problem with
(eg) `asm ("foo %1,%0"::"r","r");' in C++ (parse error from the `::')?

Now, I'm not meaning to argue with you, but I thought the extended asm
statements were pretty good.  Mind you, getting the constraints and the
operand modifiers (eg %k0) right is a PITA, especially when they're
pooly documented.  So really, just what are the fundamental flaws in the
dedisng of the asm extensions?  Maybe they can be fixed (yeah, right. I
can imagine the caos).
