Readfile on a duplicated pipe hangs

[Uwe Bonnes]

Hallo,

Marcus sent me patches that made Altera quartus install. Thanks.

Now running the package hangs in the way it communicates with created
processes.

Here is what happens in my understanding:
M: Masterprocess C: Childprocess

M: CreatePipe -> handle_read + handle_write
M: DuplicateHandle handle_read -> handle_read_dup
M: CloseHandle (handle_read)
M: Call CreateProcessA with handle_write as hstderr
M: Return Createprocess
M: CloseHandle (handle_write)
M: Call Readfile (handle_read_dup)
C: initializes, executes and exit
M: Return Readfile retval=00000001
M: Endless loop of Call Readfile (handle_read_dup) retval=00000001

MSDN says, that ReadFile should fail on an anonymous pipe, if the othe end
has close.

With following patch, the application starts up. Feedback welcome.
