That's bad news :-(

From the cygwin code (peek_pipe AT select DOT cc), I assume that PeekNamedPipe 
returns a negative value for lpTotalBytesAvail on EOF in win2k, and 0 in 
win9x.

I'll write a simple application to check that tomorrow.

BTW I looked at the putty code, and it uses a thread to read from stdin.

Well, I still think it should be possible to get notified of such an event. 
feof() from mscvrt manages to do so...
