More breakage around Rf_list*()

[eddelbuettel]

CRAN reports that BioConductor package GOSemSim no longer installs.

I can confirm this with Rcpp 1.0.4.2 too:

In file included from /usr/local/lib/R/site-library/Rcpp/include/RcppCommon.h:135,
                 from /usr/local/lib/R/site-library/Rcpp/include/Rcpp.h:27,
                 from ICmethod.cpp:1:
/usr/local/lib/R/site-library/Rcpp/include/Rcpp/lang.h:27:20: \  
   error: ‘Rf_list2’ is not a member of ‘Rcpp’; did you mean ‘Rcpp_list20’?

ICmethod.cpp:117:32: note: in expansion of macro ‘Rcpp_list2’

      |                                ^~~~~~~~~~

This is presumably another side effect of #1014 just like #1048 was (which got fixed in #1049). I will take a look. I can also confirm that Rcpp 1.0.3 does not have the issue, so we regressed :-/
