Hum, you got me.
What's that and how to check it?
From what I just reported it seems the undefined symbols are no problem
with a non threaded build (also I guess it would be cleaner not to include
all these defined thread related functions).
The problem might arise when one actually try to build a threaded lib but
ATLAS fails to pick assembly or fallback code for ATL_DecAtomicCount.
I'm currently trying to build R (it never went that far, don't remember
why) on a sparc system which failed to build a real threaded lib just like
Karl Dieter ppc system.
It's quite slow but I should be able to report today.
