#include <boost/preprocessor/stringize.hpp>

#define BOOST_PP_STRINGIZE(X)

Delays the stringization of X.

For example,

  #define NOTE(STR)\
    message(__FILE__ "(" BOOST_PP_STRINGIZE(__LINE__) ") : " STR)

  // ...

  #pragma NOTE("TBD!")

expands to:

  #pragma message("examples.cpp" "(" "20" ") : " "TBD!")

The use of BOOST_PP_STRINGIZE() above lets the PP expand the __LINE__ before stringizing it. If # would be used directly, the code would expand to:

  #pragma message("examples.cpp" "(" "__LINE__" ") : " "TBD!")

#define BOOST_PREPROCESSOR_STRINGIZE(E)

Obsolete. Use BOOST_PP_STRINGIZE().
