In my opinion, it's a mistake to run "configure" tests with -Werror. I
suggest adding such flags after configure tests have been run, as with
the --enable-Werror configure flag supported by Open vSwitch:
dnl OVS_ENABLE_WERROR
AC_DEFUN([OVS_ENABLE_WERROR],
[AC_ARG_ENABLE(
[Werror],
[AC_HELP_STRING([--enable-Werror], [Add -Werror to CFLAGS])],
[], [enable_Werror=no])
AC_CONFIG_COMMANDS_PRE(
[if test "X$enable_Werror" = Xyes; then
CFLAGS="$CFLAGS -Werror"
fi])])
I guess that -Werror=old-style-definition is somewhat more restricted,
but a similar solution can be used.
