/* These are defined by the user (or the compiler)
to specify how identifiers are imported from a DLL.
__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.
Other macros:
__int64 define to be long long. Using a typedef doesn't
work for "unsigned __int64"
All headers should include this first, and then use __DECLSPEC_SUPPORTED
to choose between the old ``__imp__name'' style or __MINGW_IMPORT
style declarations. */
