[Rcpp-devel] RcppArmadillo and 'trunc' problem

While writing some extra functions into the rmgarch package (on r-forge) 
which uses RcppArmadillo, I encountered the error relating to 'trunc' 
and 'ftrunc' already discussed here:


This occurred for the first time once I made use of Rf_exp and Rf_rchisq 
in code mixed with RcppArmadillo.

While the workaround described in the previous discussion works (i.e. 
undefine the two macros in sugar) for me, it will not work for my 
package once I release the update on r-forge.

Could you please suggest some solution or some mistake I am making which 
gives rise to this problem?
