Update for last successful build was at Wed Dec 31 15:09:06 UTC 2003.

I didn't have much luck in debugging this:

(gdb) r `cat xx.sh`
Starting program: /home/dave/gcc-3.4/objdir/gcc/stage2/gnat1 `cat xx.sh`
During symbol reading, unsupported tag: 'DW_TAG_subrange_type'.
During symbol reading, unexepected tag in read_type_die: 'DW_TAG_subrange_type'.
Die: DW_TAG_subrange_type (abbrev = 33, offset = 267998)
        has children: FALSE
        attributes:
                DW_AT_name (DW_FORM_strp) string: "atree__paren_count_type"
                DW_AT_lower_bound (DW_FORM_data1) constant: 0
                DW_AT_upper_bound (DW_FORM_data1) constant: 3
                DW_AT_type (DW_FORM_ref4) constant: 3859
Dwarf Error: Cannot find type of die [in module /home/dave/gcc-3.4/objdir/gcc/
stage2/gnat1]

This is with gdb 6.0.  With 5.3-debian,

(gdb) r `cat xx.sh`
Starting program: /home/dave/gcc-3.4/objdir/gcc/stage2/gnat1 `cat xx.sh`
internal error - unimplemented function unk_lang_create_fundamental_type called.

:(
