Because the '#define DLLAPI' in config.h.in -- from which the
config.h for Unix and Cygwin/Win32 builds is generated -- is
necessary to make the compiler happy about the modifications
to the class declarations.

When building the DLL with MSVC I need to export the classes,
and I don't think I can do that with .DEF files, so I must
put __declspec(dllexport) into the class declarations. But
because gcc will choke on them, I define them empty for gcc builds.
