[svn-r9758] Purpose:
Adding framework of N-bit filter
Description:
N-bit filter is required for NetCDF project.
To add N-bit filter, configure.in configure, Makefile.in under src and other
filter-related source code needs to be updated.
Currently, N-bit tests are turned off from the library. So the change will affect daily test.
Solution:
Platforms tested:
sol 2.7, linux 2.4, aix 5.1
Misc. update:
