DESCRIPTION

Header file for WDB XDR implementation. This header file is mean to be used
only when building runtime XDRs, it should not be used when building 
Target Server. The main reason for this WDB XDR implementation is to provide
a fully standalone WDB agent that does not depend on the runtime Operating
System source and header files.
