Well,  first  of  all  the  compiler has nothing to do with the DevCpp
developers.  The  compiler that DevCpp uses, is the Minimalist GNU for
Windows  (MinGW).  It  uses  the  GNU  Compiler  Collection  (gcc) for
compiling. Take a look at http://www.mingw.org for details.

The reason why this works, is this:

"
 Using the GNU Compiler Collection:
 
 String Literals with Embedded Newlines

 As  an  extension,  GNU  CPP permits string literals to cross multiple
 lines without escaping the embedded newlines. Each embedded newline is
 replaced with a single `\n' character in the resulting string literal,
 regardless  of  what  form  the newline took originally.
 
 CPP  currently  allows  such strings in directives as well (other than
 the  `#include'  family).  This  is  deprecated and will eventually be
 removed.
"

As you could read, it is DEPRECATED. GCC 3.2 (what I have installed) gives
the following warning for the program (older ones don't):

    warning: multi-line string literals are deprecated

Look at: http://gcc.gnu.org/onlinedocs/gcc-3.2/gcc/
and search for "String Literals with Embedded Newlines".
