GCC, stringification, and inline GLSL?

Question

I\'d like to declare GLSL shader strings inline using macro stringification:

#define STRINGIFY(A)  #A
const GLchar* vert = STRINGIFY(
#version 120\\n
attribu

To achieve this purpose I used sed. I have seperate files with GLSL which I edit (with proper syntax highlighting), and in the same time GLSL in inlined in C++. Not very cross platform, but with msys it works under windows.

In C++ code:

const GLchar* vert = 
#include "shader_processed.vert"
;

In Makefile:

shader_processed.vert: shader.vert
    sed -f shader.sed shader.vert > shader_processed.vert

programm: shader_processed.vert main.cpp
    g++ ...

shader.sed
