I'm not really familar with the PC code or with mswindows (as far as I know the 
dup() system call in windows should behave the same way as the dup() call in 
unix).
I did a quick search for Win32 error 6 and found that it is 
ERROR_INVALID_HANDLE (See 
http://msdn.microsoft.com/en-us/library/cc231199(PROT.10).aspx) so I guess the 
code is trying to duplicate a bad file handle ... which probably means that the 
file was not successfully opened  in the first place (or was closed), and you 
need to find out how/why that happened.  Since this is handle 0 (stdin) it 
really *ought* to be open/valid.
