Subject: [PATCH 1/2] maint: suppress gcc's new -Wcast-function-type in gnulib

* configure.ac (WERROR_CFLAGS): Suppress gcc's new -Wcast-function-type
warning in gnulib, because it would trigger on this:
sig-handler.h:47:12: error: cast between incompatible function types\
  from 'void (* const)(int,  siginfo_t *, void *)' \
  {aka 'void (* const)(int,  struct <anonymous> *, void *)'} \
  to 'void (*)(int)' [-Werror=cast-function-type]
return (sa_handler_t) a->sa_sigaction;
