Subject: [PATCH] Remove -Wswitch-enum from compile flags

* configure.ac (POTENTIAL_GCC_CFLAGS): Remove -Wswitch-enum, which
  requires that switch statements mention all enumerated values, even if
  there is a default clause.  Note that -Wall enables -Wswitch, which is
  the same except it's silent if there's a default clause.  The reason
  is that lightning has a number of switches like this.
