Functions do not work on c++

[GoldenStarGamer]

As I was trying to use this in cisual studio on a windows computer, I installed it trough msys2 mingw64 and the bottom part of libcue.h where functions get declared is all errors, wherever CUE_EXPORT gets called it's an error, and I cant use those functions, for example, CUE_EXPORT Cd* cue_parse_file(FILE*); is an error: this declaration has no storage class or type specifier.
