Thanks for your reply Carlos. That fixed it. What is the rational behind 
this as it seems pointers are the only thing you can add to the tree anyway.

Sorry if this is the wrong list but,
"public discussion about glibc development.  Questions or queries about 
core parts of glibc (not bugs) are appropriately discussed here."
This from the libc resources page is a little ambiguous, considering 
there seems to be no 'libc-user' list.

Andrew Ward.
