I don't set that but it shouldn't bite ...

This is pretty new code by Matt + Arun integrated by Michael. On the other
hand DATAPTR is pretty standard and defined in src/include/Rinternals.h --
which src/main/radixsort.c does not include.

Are you using gcc-5.2.* ?  It still works for me with gcc-4.9 on Ubuntu.

We could ping Michael (who integrated this) and Matt/Arun who wrote the radix
sort.
