Very true. I think this is what all related questions can be reduced to:
  1) In ANSI-C there are certain "phases of translation" which (at least
     logically) occur *before* parts of the source are "#if-ed out".
  2) There are certain sequences of input characters which have to be
     analized during this early phases and which would clearly be
     erreneous *if* they would have to be fully compiled later.
Now: Is it "required", "unacceptable" or a "quality of implementation
     issue", that such a sequence of characters in ignored parts of
     the source makes the whole program not to compile?

Note that the answer to this must be known if you have to decide what
may follow a #pragma in a "conformant program". To my understanding
#pragma-s *are* allowed in such programs *if* they are enclosed in
some #if !(__STDC__ == 1) -- #endif context.
