gcc9 has turned this warning into error when -Werror is used, lets paper
it over by turning it into a warning for now
Fixes
error: taking address of packed member of 'struct head' may result in an unaligned pointer value [-Werror=address-of-packed-member]

yeah this is new gcc9+ option , it did not occur to me. I think we
need to make the code to see if compiler supports this option before
adding it. Ideally code should be fixed but thats for laters. Drop
this patch I will add a m4 macro check and add/remove it in
Makefile.am
