It's a bug in robustbase - it redefines R_xlen_t without checking the R version. I think the author's true intention was to make it conditional on R version for compatibility so it should be using R_VERSION and not LONG_VECTOR_SUPPORT since the latter is irrelevant here as R 3.0.0+ will have R_xlen_t regardless of the long vector support.
