These 32-bit wide functions are missing in 64-bit system OS msvcrt.dll
libraries and in 32-bit pre-msvcrt40 libraries. Provide mingw-w64 emulation
as a simple wrapper around 64-bit wide functions.
On 32-bit systems, these *32i64 functions are available also under
alternative name with just *i64 suffix. So in emulation code provide also
those symbol aliases.
