[svn-r6575] Purpose:

    Code cleanup

Description:
    Re-arranged configure output for external I/O filters to show that zlib
and szlib are used for external I/O filters and display them with the output
for the internal I/O filters.

Solution:

Platforms tested:
    FreeBSD 4.8 (sleipnir)
    Linux 2.4 (eirene)
    IRIX64 6.5 (modi4)
