Hello,

I have a huge code that is running without problems under SuSE-Linux 8.0 
(gcc version 2.95.3).

When I change to SuSE-Linux8.2 (gcc version 3.3), the code can not be 
compiled anymore.

I've tracked down the problem to a very simple c++ testcase (see  below) 
that shows the same behaviour, and produces the same error message.

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

#include <fstream.h>
#include <iostream.h>

int main()
{

ofstream fout;
fout.open("solid_position.dat",ios::out || ios::ate);

return 0;
}
------------------------------------------------------------------------------------ 


The error message says (find the complete error message attached) :

hallo.cpp:13: error: no matching function for call to `
 std::basic_ofstream<char, std::char_traits<char> >::open(const char[19],
 bool)'

Since I dont want to change the syntax (iostream.h -> iostream etc.) of 
the huge code, I thought of including some old libraries during the 
linking process.
Unfortunately without success.

I would be glad, if somebody can give me a hint.
Thanks in advance
Claas
