Description

#line, #file, #file, #fileID, and #filePath are no longer special literals. They are freestanding macro expressions. The text should be revised accordingly.

Correction

Change the first sentence in the third paragraph to:

The first form of a line control statement changes the values of the #line, #file, #fileID, and #filePath freestanding macro expressions, beginning with the line of code following the line control statement.

The reference to the Literal Expression subsection should be removed and the note given after the first paragraph in the Literal Expression subsection should be included in its place.
