That one won't work. It's ABI-incompatible, mainly because it uses a
different, non-default calling convention (stdcall). Even leaving
backwards compatibility aside, we'll run again into the problems that
we had some 10 years ago in libpng, when switching between DLL-enabled
and non-DLL-enabled builds would lead to crashes, because of the
different calling conventions used across these two kinds of builds.

Best regards,
