So I should be able to safely delete all such libraries, and also any .a 
library unless I want to compile something statically.  I think I will 
stick with dynamic, including wvware, to save space, especially since 
Abiword is available for BL3 already and includes wvware.

Yes but it will not do most of what I am using it for.

Apparently this is not what you meant - see below.

I might put theses libraries in /usr/libc5 - or is there a more 
traditional place to put libc5 libraries on a libc6 linux?

Can I make a script  libc5

LD_LIBRARY_PATH="/usr/libc5" %1 %2


Then type

libc5 tifftopnm filename.tiff > filename.png  ?

Similarly for pnmtotiff pngtopnm pnmtopng.

It would be nice if libc5-dependent programs would just look in a 
different place for their libraries.  It is possible to do that?
How do other people with both libc5 and libc6 on their computers handle 
this?  I noticed that SW71 has libc5 for optional installation.
