  27 /* These are defined by the user (or the compiler)
  28    to specify how identifiers are imported from a DLL.
  29
  30    __DECLSPEC_SUPPORTED    Defined if dllimport attribute is supported.
  31    __MINGW_IMPORT          The attribute definition to specify imported
  32                            variables/functions.
  33    _CRTIMP                 As above.  For MS compatibility.
  34    __MINGW32_VERSION       Runtime version.
  35    __MINGW32_MAJOR_VERSION Runtime major version.
  36    __MINGW32_MINOR_VERSION Runtime minor version.
  37    __MINGW32_BUILD_DATE    Runtime build date.
  38
  39    Other macros:
  40
  41    __int64                 define to be long long. Using a typedef doesn't
  42                            work for "unsigned __int64"
  43
  44    All headers should include this first, and then use __DECLSPEC_SUPPORTED
  45    to choose between the old ``__imp__name'' style or __MINGW_IMPORT
  46    style declarations.  */
