In the GNU make case it is better to use ':=' instead of '=' because in the latter case there can be surprising side-effects (the RHS is evaluated on every use).
PKG_LIBS is needed exactly once, so your point is moot.

Those advices are from the CRAN maintainers, and we are very thankful. Please update your packages to implement this, there is no need to wait for another release of Rcpp, and it will only take a few minutes. There are for example a few packages that are still not using LinkingTo: Rcpp (bifactorial, cxxPack, mvabund, phylobase, sdcTable, pcaMethods) Best regards, Romain
