Ensure getline() is in scope on FreeBSD.

On FreeBSD, to make the getline() prototype visible, you must
'#define _WITH_GETLINE' before including <stdio.h>.

+dnl FreeBSD needs a bit of magic to bring getline() into scope.
+dnl We do this here rather than in (say) h/mh.h because this macro must
+dnl be defined before <stdio.h> is pulled in.
