Building a GLFW app w/ GDC on a Mac (SOLVED)

[Max Kaufmann]

Figured it out.  Just needed to replace:

version(Win32)
     extern(Windows):
version(linux)
     extern(C):

with

version(Win32)
     extern(Windows):
else
     extern(C):

I'll send a note about it to the GLFW dev guys to about the mod.
