So in episode 11, we start to get into multiple files. I grabbed the day 11 source(since I was behind it was already there) and listened it. But I found that he had no problem with calling internal and typedefs in both the handmade.cpp and handmade.h, However I got errors that all I could relate to is that it didn't know about the #define and typedef's in win32_handmade.cpp.
tl;dr:
Anyway I can get things like typedef's and #define to be defined outside of the file where defined?
I'm using Visual Studio 2013 Community Edition
If you guys need some more info, Just say so, and I'll make it so.
