>> I'm not sure why this would not have shown up before but the FreeBSD kernel reuses some standard library method names with different signatures. The file rtemsbsd/include/machine/rtems-bsd-kernel-namespace.h renames a lot of items to put them in a BSD namespace. qsort_r isn't in this list but perhaps should be.
