Backport of 4dcf0b41c687292e7b1263a679921c157ae2c22a b01f45e141afa6a89aea319a2783f177e202fa1d https://github.com/taglib/taglib/pull/77 Tested with files larger than 2GB which have been created using sox -n -r 44100 -C 320 large.mp3 synth 58916 sine 440 channels 2 sox -n -r 44100 -C 0 large.flac synth 25459 sine 440 channels 2 sox -n -r 44100 -C 10 large.ogg synth 229806 sine 440 channels 2 sox -n -r 44100 large.wav synth 6692 sine 440 channels 2 ffmpeg -f lavfi -i "sine=frequency=440:duration=244676" -y large.m4a The only file which was readable with the tagreader example before this commit was large.ogg. The problem is that long on Windows is only 32-bit (also in LLP64 data model of 64-bit compilation target) and all the file offsets using long are too small for large files. Now long is replaced by offset_t (defined to be long long on Windows and off_t on UNIX) for such cases and some unsigned long are now size_t, which has the correct size even on Windows.
