Dear Aaron,

I have just pushed a new version to Bioc svn which will trigger a new
build and a new binary linked against Rcpp 0.12.8, which will get rid of
the warning.

This should however not influence results in any way. If you observe
differences between different versions of xcms, it would be helpful to
report these versions.

Best wishes,
