As a general solution, that's not good advice, but in this case 
it's probably so. The OpenGL functions on Windows are declared 
with the stdcall calling convention, and as cdecl on other 
platforms. In D code, that means they need to be declared as 
extern(Windows) on Windows and extern(C) everywhere else. 
extern(System) is the convenient way to do that, as the compiler 
will do the right thing on each platform. Always look at the C 
headers to understand how the functions are declared before 
declaring them in D to make sure you've got the correct calling 
convention.
