I've been working on getting OpenGL to load on windows without a 
library, and encountered something curious;

Context creation fails when I try to use the function pointer 
retrieved through GetProcAddress, but works just fine with the 
statically linked version provided through 
core.sys.windows.wingdi.d.

This may be a stupid question, but why is this?

Thanks.

Odd. Just to confirm your wglGetProcAddress, is extern(Windows/System)? And it is non-null after being loaded?
