---------------------------------------------------+------------------------
 Patch to Boost Lexical Cast library, that optimizes casts to integral
 types.
 It gives performance boost about 40 times(and beats in performance Spirit
 library, when compiling with defined BOOST_LEXICAL_CAST_ASSUME_C_LOCALE),
 reduces memory usage and does not change the behavior of library.

 Patch was successfully tested on Intel 11.1.072, g++-4.4.5, VC++9
 compilers. All existaing tests for Boost Lexical Cast library were passed
 successfully.
