  33    __DECLSPEC_SUPPORTED    Defined if dllimport attribute is supported.
  34    __MINGW_IMPORT          The attribute definition to specify imported
  35                            variables/functions.
  36    _CRTIMP                 As above.  For MS compatibility.
  37    __MINGW32_VERSION       Runtime version.
  38    __MINGW32_MAJOR_VERSION Runtime major version.
  39    __MINGW32_MINOR_VERSION Runtime minor version.
  40    __MINGW32_BUILD_DATE    Runtime build date.

  44    __int64                 define to be long long. Using a typedef doesn't
  45                            work for "unsigned __int64"
  46
  47    All headers should include this first, and then use __DECLSPEC_SUPPORTED
  48    to choose between the old ``__imp__name'' style or __MINGW_IMPORT
  49    style declarations.  */
