- True ... but this is characteristic of Windows, not Ctl3d. Unfortunately,
- there is no better way to do it (without much more effort). I'm not
- up on the techniques, or if it can be done, but I assume it can ...
- Instead of linking with the LIB, looking for the DLL, and then making
- the links on the fly. (I could be way off here...)

- Because it's a Windows thigns and not a ctl3d thing, that's not really
- a good thing to do. Agreed, it's a good thing to do in the case of
- Ctl3d, but that's not where the problem is.
