+/* A C statement to output assembler commands which will identify the object

+   because we use DWARF and DWARF has an DW_AT_producer tag that does the
+   same thing.  BeOS debuggers, like bdb, that don't know about this hack
+   can get confused when they find two symbols with the same address, and
+   print the wrong one (gcc2_compiled) in things like backtraces.  The most
+   likely ill effect of disabling this is that a BeOS port of gdb would not
+   be able to tell that an executable was compiled with gcc if there was no
+   DWARF info. */
