It seems that the header boost/spirit.hpp puts the entire namespace std into the global scope. That is not very nice!

--- Example 1 --------

#include <string> #include <sstream> #include <fstream> #include <vector> #include

void f() { string s; istringstream iss; ofstream ofs; vector<int> v; }

----------------------

Example 1 should not compile (undefined symbols), but does compile. If the line #include is removed, then Example 1 does not compile.

--- Example 2 --------

#include #include

#include

using boost::filesystem::path; using boost::filesystem::ifstream;

void g() { path p; ifstream ifs(p); }

----------------------

Example 2 should compile but does not. The compiler complains that the symbol ifstream is ambigous. If the line #include is removed, then Example 2 does compile.

I´m using Boost 1.33.1 and MSVC 7.1 on a Windows XP computer.

IIRC, that comes from VC++ fatal bug about "using directive", and was already fixed under RC_1_34. -- Shunsuke Sogame
