patch 8.2.0248: MS-Windows: dealing with deprecation is too complicated

Problem:    MS-Windows: dealing with deprecation is too complicated.
Solution:   Use io.h directly. Move _CRT_SECURE_NO_DEPRECATE to the build
            file. Suppress C4091 warning by setting "_WIN32_WINNT". (Ken
            Takata, closes #5626)
