Especially in the recent CRC commits, I see
\ No newline at end of file
in almost every second file.  So, I went through
the diff between r15-1 and current trunk in gcc/, looking for
additions of such problems which don't intentional (e.g.
Wtrailing-whitespace* tests had it there intentionally) and
just added the missing newline elsewhere.
