Thanks for clarifying, Björn. I'll stick to my re-definition of the macro for the time being---these builds are hard to debug already, so I'd rather all the options be explicitly set. Adding the -UVAR bits will make the invocation similarly long, so I don't see a real advantage there either. -- Thanks, Regards, Ankur Sinha "FranciscoD" https://fedoraproject.org/wiki/User:Ankursinha Time zone: Europe/London
