    Trybos V03-05-02 has been reposited, but will wait for any resulting defect
reports to be handled before being newver'd.

    This version contains a minor change to the inheritance scheme used by
TRY_Generic_Bank/TRY_Named_Bank, and to the definition of a bank class name by
specific banks.  Now, all "primitive" methods in TRY_Generic_Bank and
TRY_Named_Bank are declared virtual.  This permits run-time dispatch to the
correct child class method, since the primitive methods are sometimes overloaded
in child classes.

    The method class_bank_name() in TRY_Named_Bank is now pure virtual, making
TRY_Named_Bank an abstract class.  The class is only intended to enforce a
policy of checking bank name consistency, so creating instances of the class
does not (and did not, though it used to be allowed) make sense.  The
implementation of this method must be provided by a specific bank class when it
inherits from TRY_Named_Bank, as it should.

    The file TRY_Package.hh has been split into five files, one for each of its
component sections.  This reduces the number of files forced to "see" constants
in TRY_Package.hh which are not needed.  The five new files are:

TRY_Fixed_Size_Types.hh         int4 type definition, etc.
TRY_YBOS_Physrec_Format.hh      YBOS physrec format constants
TRY_YBOS_Record_Format.hh       YBOS record format constants
TRY_YBOS_Bank_Format.hh         YBOS bank format constants
TRY_YBOS_Field_Format.hh        YBOS field type constants

    As of this version, Trybos now compiles with the KAI C++ compiler set to the
highest standards-compliant requirement with "-ansi", except for one remaining
error complaint.  The compiler correctly points out that the use of unsigned
integers (bit masks) to initialize enumerations is not allowed since
enumerations are restricted in range to that of signed integers.  This is a
harmless error and will be addressed in the future.  Note that we do not
generally compile our CDFSOFT2 code with the "-ansi" switch, and this error is
only detected by "KCC -ansi" at present.

    As a consequence of comparing the results of tests with the KAI and GNU C++
compilers, a number of inappropriate uses of stringstreams have been corrected.
A mistake in the TRY_Bank_Type_test.cc driver values has also been fixed.
