Yes, I think that the standard does not require a particular approach
to this problem.

Exactly.  During the first translation phase, end-of-line indicators
are converted to new-line characters.  If the majority of compilers
treats end-of-file as an end-of-line indicator (which wouldn't
surprise me), GCC can and should follow the crowd.
