* Introduce LPD3DRM_APPDATA typedef for setting d3drm appdata * Fix warning about assigning const string literals to variable char pointers * Don't cast pointers to integers on non-32-bit architectures * memset 2nd argument is int * Assume cpuid is available on x86_64, needs testing on i386 and unavailable on anything else * Store HFILE in its own member variable
