[parted-devel] next: build: turn off -Wstack-protector

[Jim Meyering]

I rebased next and got this new warning/error using
gcc version 4.3.3:

  gpt.c: In function 'gpt_read':
  gpt.c:816: error: not protecting function: no buffer at least 8 bytes long [-Wstack-protector]

So have squashed the following onto the warning-adding
change-set on that branch:
[I expect to push the result shortly]

    build: turn off -Wstack-protector

    * configure.ac (WERROR_CFLAGS): Turn off -Wstack-protector,
    to avoid warning due to libparted/label/gpt.c.
