It works for me.  Maybe it's your shell?  Remember that make uses /bin/sh to
run all of its commands.  On my system /bin/sh is really bash but maybe your
/bin/sh is something else.  Also, what version of make are you using?


  $ echo "foo:; trap 'echo \$\$?' EXIT && exit 1" | make -f -
  trap 'echo $?' EXIT && exit 1
  1
  make: *** [foo] Error 1
