[Bug c++/37671] New: can't use iostream library

["hadmanysons at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

Whenever I try to compile something using the iostream library, gcc pumps out a
lot of errors. Here's the gcc -v -save-temps screen:

gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC) 

Here's the errors i get get when compile (gcc src/mycode.cpp -o bin/myprog):
 gcc src/reg.cpp -o bin/reg

I know your page said you didn't want a code snippet but I can't help but think
it's relevant (I might just be overlooking something):

#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
  std::cout<<"asdf"<<endl;
  return 0;
}


Even something that simple won't work.
