The "make" to worry about appears to be the one in /usr/local/bin, not
/usr/ccs/bin. See the sample exploit script at the usual spot.
The problem appears to be with GNU's make, which is installed setgid (by
default) on AIX so as to enable the "-l load" option. This option is used
to throttle the number of jobs created by "make" as the system load
increases (especially during parallel makes).
I haven't checked whether /usr/local/bin/make is part of some supplemental
AIX package, or just happens to be on those systems where the admin
installed GNU make.
