/* 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.
|
|
|
|
Macros to enable MinGW features which deviate from standard MSVC
|
|
compatible behaviour; these may be specified directly in user code,
|
|
activated implicitly, (e.g. by specifying _POSIX_C_SOURCE or such),
|
|
or by inclusion in __MINGW_FEATURES__:
|
|
|
|
__USE_MINGW_ANSI_STDIO Select a more ANSI C99 compatible
|
|
implementation of printf() and friends.
|
|
|
|
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. */
