I thought what I did accomplishes the same thing.  I deleted the 2.2.5
files and then made new symlinks back to 2.1.3 using ldconfig rather than
manually deleting and remaking all the links.  Reverse order of what you
did.  Does your method accomplish something different? Can you run 'as'
without an error message now?

According to Matrix Mole, you should have been able to overwrite the old 
symlinks with -sf without needing to delete them first.  And since ln 
won't work without a couple of the glibc libraries, I don't know how you 
managed to make new links with it after deleting the old ones to these 
files.  Sln might have worked for that.

Good idea, and then symlink to them in the other directory.

But I think I may just reupgrade and give up compiling for 
BL2-with-old-library.  Other people can upgrade to use anything I compile, 
and besides you don't always need the new library.  I just used bmv 
on this computer with glibcso-2.1.3 (I think, not quite sure what I have) 
after compiling bmv on a computer with glibc-2.2.5.

James, thanks for the encouragement to keep experimenting.  You are right,
people who want something more predictable would not be doing this.  I am
glad you are finding my experimental results interesting.  I posted them
because it was hard to find such information.  I did one very long search
on how to type extended ASCII characters in linux and all I found was one
unanswered question asking how to do it.  (Same as in DOS, Alt-key plus
the ASCII number, after loading the font you are after, but you have to be
in pico or some other program which supports extended ascii, not at the
command line.)
