It is a feature of every cc(1) that will run cpp...

try

    cc -E file.c | grep '^#' | sed '1,$s/^[^"]*"//;s/"$//' | sort -u | \
    (
      echo "file.o : \c"     #  change as needed for you version of sh
	  # echo -n "file.o : "
      while read x
      do
          echo "\\\n\t$x \c"  #  change as needed for you version of sh
		  # echo -n "\\\n\t$x "
      done
      echo ''
      exit 0
    )

Which generated for me...

file.o : \
	./defs.h \
	./extern.h \
	./struct.h \
	/usr/include/assert.h \
	/usr/include/ctype.h \
	/usr/include/stdio.h \
	/usr/include/string.h \
	/usr/include/sys/types.h \
	file.c
