c - i686-w64-mingw32/include/shlobj.h 中的一些奇怪的代码

Question

我正在为 mingw-gcc 构建 openal

$ yaourt -S mingw-w64-openal

出现语法错误:

[ 38%] Building C object CMakeFiles/OpenAL32.dir/Alc/alcConfig.c.obj
In file included from /tmp/yaourt-tmp-hacked/aur-mingw-w64-openal/src/openal-soft-1.16.0/Alc/alcConfig.c:36:0:

我查看了第 37 行的 shlobj.h 并发现了以下内容:

typedef enum {
  SHGFP_TYPE_CURRENT = 0,
  SHGFP_TYPE_DEFAULT = 1,
} SHGFP_TYPE;

  SHFOLDERAPI SHGetFolderPathW (HWND hwnd, int csidl, HANDLE hToken, DWORD dwFlags, LPWSTR pszPath);

我不是 C 专业人士，但似乎 } 位于枚举 block 内，因此我尝试了所有可能的方法来修复它，但没有成功。
