I worded that poorly. It also need "and you know which values you want to
stick into your customized call of cxxfunction".

:)

Note, though, that Rcpp FAQ queston 2.4 is for a completely different
context:  a _vanilla_ C++ file with no other depends.  All your woes here are
to the non-standardness of your problem.  Which is somehting that is not as
well documented as it is, well, less standard.

Always a pleasure.
