With (bool) it's working ....

Hi Steven Watanabe,
thanks for your replay,
you are right:
unsigned int Exec(const std::string s,const bool b); should be
unsigned int Exec(const std::string &s,const bool b);

this code is written in a very short time to illustrate my problem.
So I think I have to wait until we change to MSVC 9.0

Have a nice weak
Bernd
