Caution: the extra cpp checking (the three hunks containing "Should be
one line") is manually hacked and not reflected in configure.in; do
not regenerate configure with autoconf without merging it. This
checking is required because somewhere between gcc 4.1 and 4.5 cpp
started doing regrettable things with backslash-escaped newlines.
