Switching from C::B to NetBeans and STL is gone

[patrickjm]

I was recently wooed by NetBeans' text editor so I tried transitioning my project. Using the same code and a fresh MinGW installation, I tried to compile and was greeted by a million errors claiming that all references to std::string, stringstream (atleast) were undefined. I've tried using the same compiler that C::B comes with to test and I'm getting the same errors using a compiler that, on CodeBlocks, worked perfectly. Any hints to what might be causing the problem?

I'm not entirely sure that the problem is STL missing, but it's my best guess. I've attempted reinstalling MinGW multiple times.

Here's my project compile settings. I can provided more information as needed.
