// BBGE HACK:
// Because Win32 uses __declspec(dllimport) for OpenGL function imports,
// although Core.cpp defines its own functions using the same names, which are just accessing
// OpenGL function pointers acquired elsewhere, this leads to inconsistent linkage between
// declaration in gl.h and the actual function definition in Core.cpp.
// So, we use this little hack to disable external linkage globally.
