I looked up at my g++ compiler and i found this: http://pastebin.com/VpSsEkBY http://pastebin.com/VpSsEkBY That g++ compiler is using a gnu extension through the __GNUG__ code path. The "true" C++ code path is at line 11. Edit: Answering the person below,the file that defines NULL is "stddef.h" An example of the file online that defines NULL is here: https://github.com/Alexpux/mingw-w64/blob/d0d7f784833bbb0b2d279310ddc6afb52fe47a46/mingw-w64-headers/crt/stddef.h https://github.com/Alexpux/mingw-w64/blob/d0d7f784833bbb0b2d...
