[Mingw-w64-public] _access and predefined modes
Hello according to MSDN (see https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/access-waccess?view=msvc-160) the valid modes of _access are 0, é, 4 and 6. But in io.h, we have : #defineF_OK0/* Check for file existence */ #defineX_OK1/* Check for execute permission. */ #defineW_OK2/* Check for write permission */ #defineR_OK4/* Check for read permission */ is it normal ?
