On msys2/mingw, there is no st_blocks in struct _stat64 yet, we disable the
usage of it
on msys2/mingw, and create a typedef long long blkcnt_t; for further
implementation

This makes me uneasy. Is there a guarantee that this type will never be
defined in a mingw environment (which would then result in a new compile
error)?
Can’t we just give NFSClient.st_blocks a different type, i.e. uint64_t?
Apart from that, looks good to me.
