Or your source files get white space after the "\" only when transported to Linux; this may happen if under Linux the lines of your source files still end with CR-LF (carriage return, line feed) as they do in Windows, instead of only LF (the expected end of line character in Unix).

Yeap yeap, this is exactly the problem. :) I have written a small Python program and got rid of the CR characters. The problem must have happened when the original author FTP'ed the files in binary mode from Windows onto a Unix machine. Thanks to everyone that have helped!
