I have no quibble with removing the line continuation, but the
construct your preprocessor objected to is strictly conforming
C, so you might want to queue a low-priority bug report on it.
Unmodified GCC has no problem with it (or I would have noticed
the extra backslash myself) so Apple's modifications introduce
a bug somewhere.
