Unknown.cpp: In function `int main()':
Unknown.cpp:25: no match for `BlackHole& << <unknown type>' operator


When overloading the operator<< for a class other than of type ostream, the compiler is unable to find the type of std::endl.

The compiler should be able to find the type of std::endl, since it should be a function pointer.  This happens on irix g++3.2, irix g++3.0.4, linux g++3.2, and linux g++3.0.4 (probably all 3.0+ compilers).

>How-To-Repeat:
Compile the file using g++.
>Fix:
instead of using std::endl, use std::endl<char,char_traits<char> > or 
#define endl endl<char,std::char_traits<char> >

Should I really have to do this?  This seems really wordy and a waste of time.  I would really appreciate it if someone let me know a better way to do this.

Thanks,
