    If you are looking for DWARF-2 support, you are in the wrong file.

-    gcc 2.95.3 had many configurations which prefer dwarf-1.
-    We may have to support dwarf-1 as long as we support gcc 2.95.3.

-    DG/UX (Data General Unix) used dwarf-1 for its native format.
-    DG/UX uses gcc for its system C compiler, but they have their

-    Takis Psarogiannakopoulos has a complete gnu toolchain for DG/UX
