Well, the patches should be reviewed.  Presumably he has clean copies of 
them.

This is a list of references outside installed headers.  What I want is a 
list inside such headers, after all relevant patches have been applied.

For example: there are lots of references in the installed header 
bits/string2.h at present.  So we can't move the macro out of installed 
headers until those references go away.  Does 
<https://sourceware.org/ml/libc-alpha/2015-12/msg00386.html>, together 
with <https://sourceware.org/ml/libc-alpha/2015-10/msg00265.html>, move 
all those references to a .c file or not?
