 /*
    If you are looking for DWARF-2 support, you are in the wrong file.
-   Go look in dwarf2read.c.  This file is for the original DWARF.
-
-   DWARF (also known as DWARF-1) is headed for obsoletion.
-
-   In gcc 3.2.1, these targets prefer dwarf-1:
-
-     i[34567]86-sequent-ptx4*   # TD-R2
-     i[34567]86-sequent-sysv4*  # TD-R2
-     i[34567]86-dg-dgux*        # obsolete in gcc 3.2.1, to be removed in 3.3
-     m88k-dg-dgux*              # TD-R2
-     mips-sni-sysv4             # TD-R2
-     sparc-hal-solaris2*        # TD-R2
-
-    Configurations marked with "# TD-R2" are on Zach Weinberg's list
-    of "Target Deprecation, Round 2".  This is a candidate list of
-    targets to be deprecated in gcc 3.3 and removed in gcc 3.4.
-
-      http://gcc.gnu.org/ml/gcc/2002-12/msg00702.html
-
-    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.
-    This could use more analysis.
-
-    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
-    own linker and their own debuggers.
-
-    Takis Psarogiannakopoulos has a complete gnu toolchain for DG/UX
-    with gcc 2.95.3, gdb 5.1, and debug formats of dwarf-2 and stabs.
-    For more info, see PR gdb/979 and PR gdb/1013; also:
-
-      http://sources.redhat.com/ml/gdb/2003-02/msg00074.html
-
-    There may be non-gcc compilers that still emit dwarf-1.

+
+   Some non-gcc compilers produce dwarf-1: 
+
+     PR gdb/1179 was from a user with Diab C++ 4.3.
+     Other users have also reported using Diab compilers with dwarf-1.
+     On 2003-06-09 the gdb list received a report from a user
+       with Absoft ProFortran f77 which is dwarf-1.
