MZF is written in Borland C++ 4.02. My license with them forbids me to allow you to disassemble their library to see how it works. So don't do that. (They give the source code to their library away when you buy their compiler anyway. Use that.) MZF also uses Microsoft's CTL3DV2.DLL which isn't supposed to be copied except as a part of a working program. So if you must give someone a copy of CTL3D, you have to give them all of MZF or some other program that uses it along with it.
MZF got some icons from the publicly available 3000icon.dll on ftp.cica.indiana.edu. It doesn't have any copyright, as far as I can tell. It has a lot of icons that are very similar (or identical) to the icons in commercial products. If you are a maker of commercial products and I used an icon that is yours but the cica people gave away, sorry. Write me and I will take it out of MZF. Please don't sue me until you have sued everyone who makes those 'x- number-of-icon DLLs' who is using your icon.
