This is odd. I have 

-bash-4.1$ oslevel -rq

and whilst I can't see how to get the information on the service pack, I have
service pack 2. 

https://www-304.ibm.com/support/docview.wss?uid=isg1IZ83065

dated 17th Jan 2011. 

So why am I getting the error on this bug report (ld: 0711-593 SEVERE ERROR:
Symbol C_BSTAT) and not ld: 0711-596 SEVERE ERROR? 

If I understand you correctly, you are saying ld: 0711-593 SEVERE ERROR: Symbol
C_BSTAT) was fixed in AIX 5.3 5300-10 Service Pack 3, which is dated March 24,
2010

https://www-304.ibm.com/support/docview.wss?uid=isg1SSRVAIX53TL10071505_161

That is some 10 months prior to the service pack I have. 

I suspect I am mis-understanding something. 

I'm using a 32-bit RS/6000 7025 F50, with 4 x 332 MHz CPUs, 3 GB RAM, which I
know is an antique in computer terms.
