I see two problems with this code:
1) Wouldn't "break 2" be more appropriate?
2) The use of `break' or `continue' inside `AC_*_IFELSE' (or the obsolete
AC_TRY_*) is not safe; it skips the cleanup of that macro.
Something like this is better:
...
],[
socklen_t_equiv="$t"
])
done
test -z "$socklen_t_equiv" && break
done
if -z "$socklen_t_equiv"; then
AC_MSG_ERROR([Cannot find a type to use in place of socklen_t])
fi
Have a nice day,
