RFR(S): Some AIX changes to build the complete OpenJDK on a 'vanilla' AIX system

[Volker Simonis]

Hi Jonathan,

thank you for the review.

I've enabled the AIX night build on the weekend, but without my changes for now.

This was just to check that build failures are handled and reported
correctly by our build scripts.
And indeed, the traffic lights for AIX are red today:
http://cr.openjdk.java.net/~simonis/ppc-aix-port/

But I will now checkin the changes today and so hopefully tomorrow the
traffic lights for the AIX night build () will be green.

See more comments inline..

Regards,
Volker

I still would like some input here. How does the J9 links zlib and
Xrender (I suppose J9 doesn't use freetype, right?)

Thats really strange, because we use:
xlC_r -qversion
IBM XL C/C++ for AIX, V10.1
Version: 10.01.0000.0015

I always thought compilers usually get more picky as they evolve and
not the other way round.
But perhaps you don't compile KernTable.cpp at all because you don't
use freetype? Or do you do a real OpenJDK build?
