I had problems with autotools fails on current version of MinGW64 so I wrote a minimalistic Makefile for use with MinGW64 only. It is incomplete that the "install" step is missing, but works for libserialportCS.
From some tutorial about building DLLs with MinGW64 I assume that declarion of the funtctions of the DLL as dllexport is best way. So you should also use dllimport when using the DLL.
This works with libserialportCS. Testing with C or C++ is still missing.
