[svn-r6913] Purpose:

bug fix and enhancement


Description:
combined the --simple option to the display of NATIVE datatypes
with the -S option , the print of the datatype will always display the full description
making it possible to do an automatic test for catching differences on output

made the case for printing the type of bitfield data, which was not handled

the new test generates a dataset with 10 attributes, each one a different datatype

Platforms tested:


Windows 2000 (octopus)
Linux 2.4 (rockaway)
SunOS 5.7 (arabica)
IRIX 6.5 (modi4)
