[Flac-dev] FLAC C API / Visual Studio 2008 FILE* Issue

[Ivailo Karamanolev]

I managed to get around it. I used the stream functions and provided my own
callbacks for reading and writing. What's strange is that what I've done is
just copied the contents of read/write/seek/tell/eof callbacks from the
sources to my application and it works just fine, no glitches. When I use
the build-in implementation, it just crashes without any reason. It's not a
problem to stick with my own callbacks for reading, but fixing this issue
(if it's not just me) would be nice.
