I think I understand the mount mechanism, and the binary vs text mode
mount. But I don't see the point when runing out of bash. Do you pretend
that the way I mount my drives with bash/mount changes the program
behaviour when I run it directly from Windows ? (I can hardly believe it)

I hope so. That's also the way I see the thing. The question is : What
flags ?
When using handles, I can solve the problem with fopen(f,"rb") instead of
fopen(f,"r"). And it works. But I read the whole read(2) man page (on
Linux, it doesn't exist on Cygwin) and nowhere I saw a flag that force
binary mode. Can you help ?

Anyway, thanks *a lot* for the help so far.
