I was surprised to find zsh stopped working with the release version of
B19.  The reason is that it does an fdopen(..., "w+") on a file handle
that has been duped.

Unfortunately, cygwin didn't preserve the settings file handles across
a dup.  Apparently fdopen is now checking this more stringently.

	patch from cgf AT bbc DOT com (Christopher Faylor)
	* pipe.cc (dup2): Ensure that an fd's flags are duplicated along
	with the fd itself.
