NewEnvironment is currently exposed as Rf_NewEnvironment.
R_NewHashedEnv is currrently hidden, but I'll unhide it. It does not need
a further prefix.

Rdefnes.h is a compatibility header, only used by those who want
S4-compatible macros covering some of the definitions in Rinternals.h.
Definitions can be moved from Defn.h to Rinternals.h with little trouble
as the former includes the latter (you have to be careful about
R_NO_REMAP, so declare them with Rf_).
If this is not controversial (I don't know if it is) and you want to
submit a patch there should be a description in R-exts, I think somewhere
in section 5.7 ('Handling R Objects in C').
