I an new to DJGPP and C/C++ in general. I downloaded djgpp 2.0 but it =
cannot compile my test examples. I don't know what's wrong, hope anybody =
help. all stuff with option -v are the following. Two similar examples =
give two different answers.

//myfile.cc
#include <iostream.h>
void main()
{
int a=3D10;
double d=3D10;
out<<"test\n";
out<<a<<" "<<d;
return 0;
}

>gcc -v -o mf myfile.cc
