Like i said earlier, its to do with the line endings and the way you have mounted the filesystems. ANSI standard says that nothing should follow the \ continuation character except the line feed. If you have M$ line endings, there is a carriage return before the line feed. cygwin can mount its drives in either binary or text mode. In text mode, it inserts carriage returns before line feeds to keep M$ applications happy. In binary mode it does not. You need to ensure your sources are on a binary mount point and you do not corrupt your sources by using a editor which inserts carriage returns.
