Again C++ question

[Claudiu ANGHEL]

You are mixing C++ streams with C file libraries. You should consider 
ofstream::open. In c++ reference I do not find the constructor 
ofstream(int) but on msdn yes (non standard feature?!?!).
It is possible that was an already deprecated feature and gcc discarded 
it. Noting to do with kdevelop but gcc.
