If it's a C++ DLL, there are some issues with name mangling, IIRC.
Otherwise, you simply declare the functions as you normally would and
supply a "-lCOM" flag to the linker (provided your DLL is named "COM.dll";
you may also need to add a "-L" flag pointing to the DLL's directory).

In a more complex case, I believe you can use "dlltool" to create an
import lib (COM.dll.a).  Read up on "dlltool" for details, and see, e.g.,
Cygwin source code for some examples.
