it's 2.61

uhm yes

on opensolaris the PATH begins with /usr/gnu/bin, so we are talking
about the GNU rm see:
(sorry for this i always get lost in PATH's)

sartek at osol:/tmp/a# mkdir -p
asdasd/asd/as/d/asd/asd/asd/asd/asdasd/as/das/das/da/sdas/das/das/da/sd/asd/asd/asd/as/das/d/asd/asd/asd/asd/as/das/d/asd/asd/asd/
sartek at osol:/tmp/a# which rm
/usr/gnu/bin/rm
sartek at osol:/tmp/a# rm -rf asdasd
rm: cannot remove directory `asdasd': Directory not empty
sartek at osol:/tmp/a# /usr/bin/rm -rf asdasd
sartek at osol:/tmp/a#
