  Sorry, cut'n'pasto.  There should be a 2>&1 before the other two
redirections - here's the exact line from my command shell:


/artimi $ mkdir -p LOOK_HERE_FOR_SYSTEM_DIR &&  gcc -v -E - 2>&1 </dev/null
>/dev/null -isystem LOOK_HERE_FOR_SYSTEM_DIR | grep -A1
LOOK_HERE_FOR_SYSTEM_DIR | tail -1 
/usr/local/include
@_______. .
(       /"\
 ||--||(___)
 '"  '"'---'
/artimi $



    cheers,
