Or have WINE installed (it even worked with the 0.9.20 version I've
got installed). I had it make a 4.1GB file which sndfile-info
identified as :

Version : libsndfile-1.0.20

========================================
File : /4GBwav/Stereo4Gb.wav
Length : 4295837820

Strangely enough libsndfile-1.0.23 borks on the file:

Error : Not able to open input file /4GBwav/Stereo4Gb.wav.

   Table length : 0
*** Unknown chunk marker (0x0) at position 0x34. Exiting parser.

Error in WAV file. No 'data' chunk marker.
