I am making some changes to the native compiler for my Master's project, and I have found myself in a situtation where I can compile the native compiler itself ("make opt"), but do not seem to be able to recompile the native compiler itself ("make base.opt").  The error message is identical to the message mentioned at http://caml.inria.fr/mantis/view.php?id=6344; however, doing a "make bootstrap" and/or following the "Hard bootstrapping" sequence in the top-level Makefile does not seem to help.  Interestingly (or perhaps coincidentally), if I go back a couple of commits, then I can build al the way to "make opt.opt", but I am not sure if I can somehow use the native compiler to help me bootstrap the next version of the native compiler.

I am not sure I see how the changes I made would cause misbehavior in the main path of  the compiler (I am essentially adding a few extensions to Lambda and Ulambda -- but my extensions, as near as I can tell, are isolated from the standard OCaml language constructs).
