// Notes:
// -F46838.4<klr> Ported -td option from toJava.
// -10/17/98 KLR Ported fix for d48911 from toJava
// -10/18/98 KLR Ported fix from toJava for "unsigned long" constants
// -F46082.51<daz> Removed code to collect makefile list generation inforamtion
// from getStream(); see f46830.
// -F46082.51<daz> Removed -stateful feature: methods javaStatefulName(String)
// and javaStatefulName(SymtabEntry) are obsolete, supplanted by javaName().
// -D54640<daz> Represent unsigned long long expressions with their computed
// value rather than their actual representation (see notes in method
// parseTerminal(), parseBinary(), and parseUnary().)
// -D58319<daz> Add getVersion() method.
// -D48034<daz> Import Helper classes for typedef struct members when generating
// helper. See method addImportLines().
// -D59851<daz> Modify to enable QuickTest build. (pending)
// -D42256<daz> Determine import lines for template types, which may specify any
// positive int., constant expression for a boundary. Such expression containing
// non-literal contansts previously caused problems when appearing in constructs
// structs, unions, exceptions, typedefs, operation types and parameters,
// attributes; and of course, sequences, strings.
// -D59063<daz> Add helper for global exception to stub import list.
// -D58951<daz> Publicise members for QuickTest.
// -D59421<klr> Change ValueBaseHolder to SerializableHolder
// -D59596<klr> Prevent accesses to elements of empty Vectors.
// -D59771<daz> Add import stmt for Helper of global type in stubs.
// -D59355<daz> Remove target dir. from filename when writing to prolog.
// -D59437<daz> Fill typename information for value boxes.
// -D62023<klr> Don't import ValueBase*
// -D62023<klr> Add corbaLevel
