__DECLSPEC_SUPPORTED Defined if dllimport attribute is supported.

__MINGW_IMPORT The attribute definition to specify imported

variables/functions.
|
|
_CRTIMP As above. For MS compatibility.

__MINGW32_VERSION Runtime version.

__MINGW32_MAJOR_VERSION Runtime major version.

__MINGW32_MINOR_VERSION Runtime minor version.

__MINGW32_BUILD_DATE Runtime build date.

__int64 define to be long long. Using a typedef doesn't

work for "unsigned __int64"
