No one has asked about it before; I can ask, but suspect that since
there is a difference in existing implementation, it would be easier for
POSIX to standardize a different function name than qsort_r than to pick
sides on which signature to standardize.
My personal preference is the glibc style (the opaque argument last in
both qsort_r and the comparator), not the BSD style (the opaque argument
first in both calls), This is because POSIX already has other
standardized functions in the glibc style (pthread_cleanup_push,
pthread_create), and none in the BSD styloe.
