Yes, it is the programs and libnetmp and libtiff and libpng which you 
compiled.  Without the libc and libm and ldlinux for BL2 - a combination 
of netpbmbl and netpbm3, which I will delete soon along with netpbm2, when 
I edit my file description blfiles.htm.  Netpbmdocs stays.

Can you rewrite ppp-on with -f, and replace some of the modules in the 
2-floppy ramdisk with what you actually use, and save the new image file? 
I did that to preserve my settings.

Do you get a better download speed with other modems?  I generally get at 
least 49K connect with a 56K modem.

That is pretty good, from sdf, which tends to download slowly.

I have discovered that ftp uploads are a steady 3.1K, while kermit file 
transfer is very unsteady and stall a lot, averaging 1.5K.  More errors 
than transmitted blocks.  Maybe less than 30 window slots would help?
Uploading that same file took me about 30 minutes.

Did you get it to work properly?  I recall something in it not working 
quite right, even after a bug was fixed.  Try any switches.

There was a way to compile not stripped (with information left in the 
binary).

I tried to use the latest image libraries because they may have come up 
with new formats or fixed bugs. One of my programs (links2?) needs 
libpng.so.2 so I deleted the older libpng and made a symlink to 
libpng.so.3 (the opposite of what you suggest).  Why not just install my 
package of dependencies?

What is upc?

How would you go about converting BL3 to just libc6?  Many of Steven's 
programs are statically compiled but not all.

Thank YOU, it would not exist without your help and with luck I can now 
use my setup to compile other things.  C++ appears to still be a problem 
and will remain so unless I want to upgrade that compiler, which if I had 
to upgrade glibc would take even more space.  Or can you compile gcc-g++ 
against uClibc?

I want to make a smaller package including only the files that I had in 
the libc5 package (plus pnmtolj for color printing).  If I have all the 
libc5 files that I want in /netpbm-libc5 and want to copy selected libc6 
programs of the same name, currently  in /netpbm-libc6,, can I do this 
with a script?

for i in `ls netpbm-libc6/*` do ....   cp -a ...
???
