agreed,  either both lib/header or neither...

Note that (gcc) "make install-html" installs "libiberty.html" into  
the doc dirs which says (amongst other things):

-- that the library is used by "various GNU programs"

--  " Passing --enable-install-libiberty to the configure script when  
building libiberty causes the header files and archive library to be  
installed when make install is run. 
This option also takes an (optional) argument to specify the  
installation location, in the same manner as --prefix."

I've not used that configure argument to gcc [ it's not listed by  
(gcc) configure --help  or on  http://gcc.gnu.org/install/ 
configure.html  ] so presumably the html refers only to building the  
library as a separate project.

I'd add my £0.02 - and say if it's installed at all - it would make  
sense for it to be installed along with the other gcc-version- 
specific .a files in lib/gcc/X.Y.Z
That way the user can keep track of which version is being linked.
