Re: new image library "requirements"

[Richard Stallman]

    Yes but not without inconvenience.  If he doesn't want images and hasn't got
    the headers for gif, tiff or png then configure presumably aborts three
    times until he finally uses:

    configure --without-gif --without-tiff --without-png

I agree with the proposal to indicate all such errors together, not
just the first one encountered.  That way he just needs two tries to
get it to configure right.
