I can see one difference between ISE and Gobo when opening
the file under Linux/Unix. When opening a binary file,
Gobo does "rb" (same as Windows) whereas ISE does "r"
for the mode. I guess this is the problem. I will fix that
and we will see how it goes. In the meantime I'd be interested
if you could have a look at the manpage for fopen() on Linux
and see if there is anything specified for "rb" (like "open
the file in case-insensitive mode" ;-)).
