Okay, this is probably the case for a traditional-mode or
lenient-mode switch (where lenient-mode would, as I tried
to express in the bug report I could not create, not be
as restricted as traditional mode, but more useful than
C99 mode – for example like gcpp -x assembler-with-cpp).

Right. For the single-quote case, an example like
│tg@bleu:~ $ cat >testfile <<'EOF'                                                  \
 │> if (rec != '')                                                                  \
 │> second\                                                                         \
 │> line
│> EOF
│tg@bleu:~ $ /usr/libexec/cpp <testfile                                             \
 │# 1 "<stdin>"
│if (rec != '
│')
│secondline
is enough to trigger what I *still*, despite C99, consider a bug.
Where does that newline come from? (Similarily, where do these
newlines at the beginning of the file come from?)

The case for the double-quote bug is appended. Reiser CCCP does
the right things, except (feature or bug?) it doesn't even con-
catenate the split lines. GNU cpp does the right things as well.
pcc cpp fscks up big time.
