#291 advzip: "Failed tell" error for ZIPs larger than 2GB in size

[ZiNgA BuRgA]

When using advzip to generate a ZIP larger than 2GB in size, I get the error:

Failed tell on example.zip [at void zip_entry::save_local(FILE*):zip.cc:635]

I'm using the supplied Windows x64 build, version 2.1

It seems like fseek/ftell isn't reliable for files larger than 2GB: https://stackoverflow.com/questions/16696297/ftell-at-a-position-past-2gb
