* builtin.c (do_dump_node): Add the size of each object to
the printout.
+ Unrelated: Make things works when built on systems without
+ the GMP and MPFR libraries. Thanks to Thomas Trepl <ttrepl@yahoo.de>
+ and Bruce Dubbs <bdubbs@linuxfromscratch.org> for the reports.
+
+ * awk.h (struct exp_node): Add alignment padding when we don't
+ have MPFR. This is a hack, pending a total refactoring of
+ the NODE structure.
