I originally insisted on >& because it worked on tcsh, but since make uses /bin/sh and /bin/sh has to be POSIX compliant, we can use the POSIX variant. >& is not POSIX compliant, but >/dev/null 2>&1 is POSIX compliant. This is specified in SuSv3, Shell command language, sections 2.7.2 and 2.7.6. >>>> Signed-off-by: Stephan Guilloux <[email protected]> >>>> > > Acked-by: Ward Vandewege <[email protected]> > Stephan, would you mind resubmitting the 2>&1 variant?
