Re: AIX 4.3.3 has make sgid 0?

I was browsing the SecurityFocus vulnerability database and found the following:
"Because the make utility is reported to run with setGID root privileges, a local attacker may potentially exploit this
condition to gain access to the root group"
Is this true ? I cannot believe that IBM has an setGID root-bit on the make utillity. This goes against all security
practices I've ever heard.
Are there people that have more info on this vulnerability or is this a hoax?
make is *not* setgid on my AIX 4.3.3 ML 11 box:
# echo `uname` `oslevel -r`
# ls -l /usr/ccs/bin/make
-r-xr-xr-x 1 bin bin 90362 Sep 26 2002 /usr/ccs/bin/make
# lslpp -L bos.adt.base
bos.adt.base 188.8.131.52 C Base Application Development Toolkit
Out of curiosity, I pulled apart the bos.adt fileset from the 4.3.3
distribution media. In the bos.adt.base.inventory file, make is
specified as mode 555 and is not setgid there either:
owner = bin
group = bin
mode = 555
I guess it's possible that one of the filesets between 184.108.40.206 and
220.127.116.11 is different but I'm not about to find out...
