+modification history
+--------------------
+01g,29apr10,pad  Moved extern C statement after include statements.
+01f,18jan10,rlp  Added UNDEF_SYM and COMMON_SYM for symbol management.
+01e,24feb09,jmp  Added 64-bit support.
+01d,07mar05,v_r  Cleanups + code conventions compliancy work.
+		 Moved SYMBOL structure back into public header as needed by
+		 published APIs.
+01c,18sep04,jn   Move toward shared code on host and target
+01b,01apr04,jn   Fix display of symbol types
+01b,17feb04,pad  Extended symbol's group field from 16 bits to 32 bits (to
+		 support shared libraries).
+01a,29oct01,jn   created from HIDDEN part of symbol.h
