Thanks.  But I wanted to ask you to change the source of `fopen' so that 
it tries to call `open' once in compatinility mode, and if that fails, 
call it again with DENYNONE bit.  Can you please do that and see if that 
solves the problem?

I don't know any other way than to look at undocumented DOS structures, 
which will not work in Windows 95 or Windows 3.11 with 32-bit file access 
enabled.
