KRB5 1.5 or 1.6 compiled on AIX 5.2/5.3

Hi,

	I too am trying to build MIT kerberos 1.6.2 for AIX 5.3.(yes I know.
I'm sorry too.) I've gotten it to build by building as described below,
but a bit of looking into this led me to discover the real reason the
link step is failing without -brtl.

it seems that the AIX linker search mechanism only treats files with the
.so extension as libraries if -brtl (run time linking) is used.

I believe that libtool deals with this by generating both a .a version
of the library(using ar) and a .so version of the library(using xlc with
the -brtl switch).

I'm not sure exactly what the right answer would be, but simply creating
links to the libraries with the .a extension should allow the compile to
complete.

That said, I have another problem.

after compiling with the -brtl flag, the "kdb5_util load <file>" command
  fails with the following error:

queen% /usr/local/sbin/kdb5_util load /home/ma3d/secret/k5db.dump
load: Unable to load requested database module 'db2': plugin symbol
'kdb_function_table' not found

I think my next step will be to re-build without optimization, and try
and see what's going on in the debugger, but I also figured that I'd see
if anyone else had any helpful suggestions.
