The main problem is working out which flags the AIX loader requires,
e.g. -Wl,-brtl to allow libraries with the .so suffix to be found, or
-Wl,-bbigtoc to increase TOC space. The process is rather labourious as
the whole configure-make cycle takes such a long time. Thus, if part of
the make fails at some point and I find that some flag is missing, I
sometimes just rerun the command which failed and then run make
again. Another problem was that setting the option -Wl,-G to avoid a C++
problem caused the next configure run to produce completely spurious
results and subsequently a whole lot of other compilation errors.

Of course, I am solely to blame for shooting myself in the foot by
trying to cut corners and save time. However, I would like to find the
correct environment settings that would allow make to run without error
and would be happy to document this on the Octave wiki.

Thanks for the help and interest
