This looks very much like the typical CR+LF (*) error.  GCC used to
fail when processing files that were not uniform in using CR+LF or
just LF for line breaks.  When finding a CR, it would sometimes
interpret that as whitespace after `\', and not merge the lines
together, resulting in this kind of error.  Please make sure this file
doesn't contain embedded CRs and try again.

* CR stands for Carriage Return, or ^M, ASCII 13, whereas LF stands
  for Line Feed, ^J, ASCII 10.
