Yes, that's right. There's no need to adapt the build system to create
DLLs with MinGW/Cygwin. Libtool already takes care of it. The
dllexport/dllimport dance is necessary to mark/access the symbols that
are exported by the DLL. All untagged symbols are usually hidden, except
a .def file is used to list the exports. If the functions are supposed
to be dynamically loadable, e.g. with LoadLibrary and GetProcAddress,
they should be tagged accordingly.
