Does not support 64bit systems.

If I try to split a wav file I get the follwing message:

Only supports PCM wave format
tag = 44100, PCM = 1

It works on the same file with the 32bit version. I think the reason is that some headers are 32bit long but read as 64bit variables. I compiled a version for myself where I used 32bit variables and this enables me to split files. I do not want to present this patch here because it is incomplete and has bugs (the file size isn't displayed correct) and I have to few knowledge about the wav file format and correct 32bit datatypes. If I have time and a fix isn't released I will rework this patch.
