[flac-dev] A small build fix for some MinGW toolchains

[Виталий Новичков]

Hello!

Many years ago I have found some bugs are prevented build of libFLAC on 
some MinGW toolchains and I made my own patch to fix that.

- The `_wutime64()` call may absent. For this case I using the 
`_wutime()` call as a fallback when _wutime64() is unavailable.

- `_stricmp` and `_strnicmp` are also may fail. Therefore it's prefer to 
use `stricmp` and `strnicmp` (without `_` prefix) on MinGW toolchains.

I have added a small check into CMake build, however, I didn't touched 
Automake and MSVC builds yet. Anyway, for MSVC builds you can simply 
define the `HAVE_WUTIME64` macro if MSVC toolchains are always have that 
call available.

I have included a patch and a simple test program which tests 
availability of `_wutime64()` call.

Can you apply my patch or make a different fix of this issue?


Best regards,
