[Rcpp-devel] Problem with RCPP Paralell

[Kevin Ushey]

Hello Roberto,

A new release of RcppParallel (5.1.7) was just published to CRAN, and
I'm hopeful that this release will resolve the compilation warnings
you (and other package authors) have seen when trying to use
RcppParallel. Please let me know if you have any further trouble.

Thanks,
Kevin
