+As of GCC 4.1, @env{DWARF2} exception handling is available on HP-UX. 
+It is now the default.  This exposed a bug in the handling of data
+relocations in the GAS assembler.  The handling of 64-bit data relocations
+was seriously broken, affecting debugging and exception support on all
+hppa64-*-* targets.  Under some circumstances, 32-bit data relocations
