Some legacy codes rely on allowing @code{READ} or @code{WRITE} after the
EOF file marker in order to find the end of a file. GNU Fortran normally
rejects these codes with a run-time error message and suggests the user
consider @code{BACKSPACE} or @code{REWIND} to properly position
the file before the EOF marker. As an extension, the run-time error may
be disabled using -std=legacy.
