    commit c62684cccbcdb159d50be781d0db27bdbd16bcc7

    Changes in source are inside comments. No
    logic change.

    This now works better.

    The problem was that @file was empty
    and @page was dwarf.h (or libdwarf.h)
    so effectively @fail matched @page. Duplication.

    Now we do not get warnings from latex about
    duplicate hypertargets from dwarf.h or libdwarf.h .
    A result of changes below to doxygen comments.

    Ensuring @page and @file appropriately different
    to avoid duplicate entry warnings from latex.
    Removed a stray /x in a doxygen comment.
            modified:   src/lib/libdwarf/libdwarf.h

    Unfortunately still true that rerunning
    doxygen and latex  do not result in
    the same size of libdwarf.pdf, even
    if nothing changed.

    commit 165ab8d2588ad3f64c2ca8d6ccd629710c873f51

    Now for dwarf_set_frame_rule_initial_value() and similar
    check the Dwarf_Debug argument is non-null and
    a real (not pointing to a zeroed structure) pointer.
            modified:   src/lib/libdwarf/dwarf_frame.c
    Added new field in Dwarf_Debug so after a change
    to the frame rule etc settings the next access to
    frame data will check that these settings are
    an acceptable combination, else it will
    return DW_DLV_ERROR.
            modified:   src/lib/libdwarf/dwarf_opaque.h
    Mention that a null Dwarf_Debug argument will
    cause these little functions to return zero
    as the 'previous' value in doxygen comments.

    commit f5b5429ac5bf58e20943da45043284043aefd7a3

    Ensure that all initial entrances to reading Frame data
    call _dwarf_validate_register_numbers() early on
    to be sure that table sizes and same-value etc
    follow the rules.
    A couple cases this was not done before now.

2026-01-26:  David Anderson
    commit 78060b72a06fb5fa3cfd9731ec8736689fade804

    Now dwarf_set_frame_rule_initial_value() interprets
    dw_value argument as meaning 'just return current value,
    do not change the initial value setting'.
    It was an ommission to fail to do this days ago.
            modified:   src/lib/libdwarf/dwarf_frame.c

    Now dwarf_iterate_fde_all_regs3() calls
    _dwarf_validate_register_numbers() so we return error
    rather than try to run frame data with bogus
    user settings of frame register defaults.

    commit 84511baec5d26856914476d23645c247eff2a72c

    This is used in 'make rebuild' to create C source
    for libdwarf based on information read from dwarf.h
    and libdwarf.h.  In a Cross-build to Arm ABI the compiler
    warned of careless comparison of signed to unsigned.
    Fixed now with completely safe (in
    this context) cast to signed long.
