You guys make life fun ;-) (Yes, note the sarcasm). So you define
these external functions INTO the compiler itself... an interesting
design...

Looks like I'll have to figure out how to break up the build system to
build JUST the ocamlc compiler and nothing else; use system tools for
everything else.

Is this to ensure your particular implementation of stdlib is
guaranteed to work? As I noticed an interesting error when trying to
build a custom compiler the naive way:

Error while linking ../../stdlib/stdlib.cma(Pervasives):
The external function `caml_ml_input' is not available

Anyways, I assume you did it like this for a good reason.
