Hi,

Following Jim's suggestion I have split my original rather large
multiple comp unit header patch into several parts. Here is the first
one which moves the DWARF abbreviation table into the comp unit header
structure with several relevant changes. Note that some changes may seem
overkill, but they are place makers for the subsequent parts.

2002-07-12 Petr Sorfa (petrs@caldera.com)

        *  dwarf2read.c (ABBREV_HASH_SIZE): moved definition
           forward in the code to be defined before
           struct comp_unit_head.
           (comp_unit_head): Added several new members,
           some are being used with this patch, some not.
           offset - Offset of the cu_header in .debug_info
           begin_offset - Base offset of cu_header into program
           next - Next comp unit head in program
           dwarf2_abbrevs - abbreviation tables associated with
           comp unit header.
           (dwarf2_abbrevs): Removed from global var space to
           comp unit header struct.
           (dwarf2_read_abbrevs): Now accepts a cu_header
           parameter and to handle the dwarf2_abbrevs inside
           the cu_header.
           (dwarf2_lookup_abbrev): Now accepts a cu_header
           parameter and handling of dwarf2_abbrevs inside
           the cu_header.
           (dwarf2_build_psymtabs_hard): Changed to support
           the new comp unit header.
           (psymtab_to_symtab_1): Changed to support the
           new comp unit header.
           (dwarf2_empty_abbrev_table): Now expects a ptr
           to a dwarf2_abbrev table to clean up.
           (read_partial_die): Now supports the call to the
            new dwarf2_lookup_abbrev.
           (read_full_die): Now supports the call to the
            new dwarf2_lookup_abbrev.
