When linking iconvdata I still get the following failure.  (Both with
and without the patch you mentioned in the email just to me).

/newgnumnt/build.glibcfix/libc.so.0.3: undefined reference to 
`size_of_encoded_value'
/newgnumnt/build.glibcfix/libc.so.0.3: undefined reference to 
`read_encoded_value_with_base'

Some quick details on my config - I still have both build trees (with
and without your patch) if you need more info:

gcc version 3.0.2, binutils 2.11.92.0.12.3 20011121

`That's what you said last time we met' said Arthur.
`They were,' said Slartibartfast.
`Yes, that's true,' admitted Arthur.
