             Fix For: 0.13.0


hi , Gens:

    thrift compiler will not auto update gen-cpp directory.

     when we call  t_generator::generate_program() and init_generator() in compiler\cpp\src\thrift\generate\t_generator.cc ,  #define MKDIR(x) will ignore EEXIST, throw on any other error, this will not give any reponse print on terminal. 
     used to be update the whole directory.
     code details:

{code:java}
// ignore EEXIST, throw on any other error
#ifdef _WIN32
#define MKDIR(x) { int r = _mkdir(x); if (r == -1 && errno != EEXIST) { throw (std::string(x) + ": ") + strerror(errno); } }
#else
#define MKDIR(x) { int r = mkdir(x, S_IRWXU | S_IRWXG | S_IRWXO); if (r == -1 && errno != EEXIST) { throw (std::string(x) + ": ") + strerror(errno); } }
#endif
{code}

Thanks.
Zhouhu.
