So the problem is that an xargs variant would not support spaces in 
filenames. Configure already fails before the first printout if there 
are spaces in the path to the root repo so that shouldn't be an issue. I 
very much doubt we would make an effort to support that use case. The 
drawback of the current solution is that if we introduce a new use of 
FIND_DELETE, we will most likely forget about the error if the find 
returns nothing and you will have to fix it again for AIX. I'm fine with 
either solution and will happily leave it for you to decide.

I took your patch and ran it through JPRT successfully so it has been 
tried on all our platforms.
