I'm sorry, Anthony, I misunderstood what you were doing.  Most of the 
work for "shadow" headers has already been done, and is in the tree
under /shadow, along with scripts mkshadow and inclosure.  It just 
needs to be finished, including ...

There's no problem with staging the work.  Send patches for what you 
have, and later patches for the rest.  We will need to hack up the 
configure system to allow us to choose whether to install your
(initially incomplete) shadow headers.  When they're done, we can 
make that the default if configure doesn't find glibc headers with 
the work already done in them.
