Or else what?  Speaking of semantics!

If an implementation conforms exactly to the Standard, EXCEPT that it
happens to support some extension like

	#pragma allow_some_crappy_old_aberration_from_1981

which, IF you include that line, allows it to compile a non-conformant
program, then do we cry "ooh! bad mans!" and deny conformance to the
whole product?

In other words, must a conforming IMPLEMENTATION be incapable of
accepting any kind of nonconforming SOURCE PROGRAM, no matter what
extra control switches you feed it?

If so -- if vendors would be unable to claim ANSI conformance for any
new compiler release which retains any special backward compatibility or
special extensibility -- then the Standard will be the VERY proud
sovereign of a VERY tiny kingdom indeed... :-)
