[ewg] duplicate member error when building infinipath-psm-3.1-364.1140

Thanks for pointing this out.  
A PSM developer tells me that you can remove that line 81 from source, and re-compile.

Can you file a Bug on this at the Open Fabrics Bugzilla?
Product: Open Fabrics Linux
Component:  QIB driver   ( I see that there is no PSM component;  I'll try to get that fixed)

[Tom] 
We don't subscribe to that philosophy. :) 
The fact that the code should compile warning free is part of our assurance of quality.  If a user is encountering a warning we didn't, we don't want that to be a silent event.  If the user wants to press on and ignore an error, they can remove the -Werror flag.

Cheers,
Tom
