Need Help with a makefile

[ChronoCross]

I'm currently using a cygwin unix shell on my computer and I need to compile a dll from source. Unfortunately I lack any makefile experience. Can anyone help me out.

List of files

Main File: bsn.cpp
bsnpreset.cpp
nencode.hpp
nenreg.cpp
nenreg.h
tg.cpp
tg.h

Any help would be greatly appreciated. btw i installed all available packeges to full for cygwin.

Thanks in advance.
