--- Comment #11 from Sam James <sjames at gcc dot gnu.org> --- C99 seems to explicitly say, within Clause J.2, in the second bullet point: > >1 The behavior is undefined in the following circumstances: > > [...] > A nonempty source file does not end in a new-line character which is not > >immediately preceded by a backslash character or ends in a partial > >preprocessing token or comment (5.1.1.2). Came across this because Clang has this warning for -pedantic but GCC doesn't.
