Don,

This looks good.  Please have a look at my comment below.  If that isn't 
feasible, then please check it in.

If these are the only changes necessary to go from 4.1 to 5.0, it looks 
like they are pretty similar.

Since we don't actually use ippCoreGetCputype/ippGetCpuType in the 
library, i.e. we only use it to determine if IPP is present, is there 
another function that we could check for that is the same in both 4.1 
and 5.0?  Then our configure check would be even simpler.
