declarations in non-exported headers and embedding R

Hello, I've been using R embedded in PL/R (R procedural language handler for PostgreSQL, http://www.joeconway.com/plr/) very successfully for several months now. A sincere "thank you" goes to the R development team for such a great product. I have a question I'm hoping someone here can help me with. In order to get the required functionality out of PL/R, I've had to resort to using some defines and declarations that are only available in non-exported headers. There is precedent, of a sort, for most of what I've used in the tests/Embedding source. Below I'll present the header code I've used, where it comes from, why I've used it, and where I saw it used in tests/Embedding. My question is whether there is equivalent exported functionality that I'm missing? Or if not, would a patch be accepted that moves this functionality to an exported header?
Some of it is certainly a well-known shortcoming of the set of
exports. E.g. tcltk.c has had
/* From Parse.h -- must find better solution: */
#define PARSE_NULL 0
#define PARSE_OK 1
#define PARSE_INCOMPLETE 2
#define PARSE_ERROR 3
#define PARSE_EOF 4
SEXP R_ParseVector(SEXP, int, int *);
for a couple of years (not that it gets much use since that interface
is mostly in the opposite direction). Adding an Rembedding.h or so could
be a good idea. However, it's not really my field of expertise and a
couple ofother R core members might have strong opinions on what
should be made available and how...
