I am using Netbeans 7.2, and I have downloaded GCC 4.7 using the Cygwin setup. I have also added the directories to my PATH and I believe configured the settings in NetBeans appropriately. No matter what I do, I get the error: 
-std=c++11 not recognized. 

This line, from source code that I need to use, is particularly causing problems:

```
using size_type = long unsigned int;

```

Is this specific to c++11 syntax?
