   I thought <link.h> is already removed from the list of installed
   headers.  Nobody outside the libc should ever use it.  It's changing
   constantl and the variables referenced are not visible anyway.  Can
   anybody name a user?

Yep, GDB uses it, probably ever since it supports debugging ELF shared
libraries.  The header seems to be available on all SVR4 derived
systems and on ELF based *BSD systems too.  The comments in our
<link.h> explicitly say that it is intended to be used by the
debugger.  There is even a comment saying that most symbols of `struct
link_map' may change without notice, implying that the few listed
before that point won't.

I would strongly object against removing it.
