AIX class library changes - update and questions

[Lindenmaier, Goetz]

Hi Steve, 

yes, in both cases we would follow your approach.

In the hotspot code we anyways (mostly) use AIX without underscore, and we
will adapt the jdk accordingly.

Also we should use the Open Source packages, and the standard path settings.

Yours,
 Goetz & Volker

Subject: AIX class library changes - update and questions

Hi  all  - quick update and some questions.

I've been going through the IBM and SAP changes and building them incrementally.  I'm not finished yet but I wanted to float a couple of questions.

1 - use of #ifdef _AIX  versus  #ifdef AIX.        SAP uses "_AIX" while IBM uses "AIX".    For other platforms we see  "__linux__" or "__solaris__"        

Any preference on  _AIX vs AIX or something else?    Currently I'm using AIX and changing any _AIX I  find.   

2 - We are relying on Open Source packages for some of the tools  (find for instance).      I'd like to make sure we are all using the same set of packages and that their installed location is the same - OR -  we just agree that PATH has to be set correctly first :-)  

A concrete example:  I noticed that  SAP's common/Defs-aix.gmk file has a hard coded  reference to find being in '/usr/local/bin'     If you use the oss4aix packages then the relevant RPM installs find into '/opt/freeware/bin'

Any thoughts on this ?
