/* Read the initial length from a section.  The (draft) DWARF 3

   or 12 bytes.  If the first 4 bytes are 0xffffffff, then the next 8
   bytes describe the length and all offsets will be 8 bytes in length
   instead of 4.

   An older, non-standard 64-bit format is also handled by this
   function.  The older format in question stores the initial length
   as an 8-byte quantity without an escape value.  Lengths greater
   than 2^32 aren't very common which means that the initial 4 bytes
   is almost always zero.  Since a length value of zero doesn't make
   sense for the 32-bit format, this initial zero can be considered to
   be an escape value which indicates the presence of the older 64-bit
   format.  As written, the code can't detect (old format) lengths
   greater than 4GB.  If it becomes necessary to handle lengths
   somewhat larger than 4GB, we could allow other small values (such
   as the non-sensical values of 1, 2, and 3) to also be used as
   escape values indicating the presence of the old format.

   The value returned via bytes_read should be used to increment the
   relevant pointer after calling read_initial_length().

   [ Note:  read_initial_length() and read_offset() are based on the
     document entitled "DWARF Debugging Information Format", revision
     3, draft 8, dated November 19, 2001.  This document was obtained
     from:

	http://reality.sgiweb.org/davea/dwarf3-draft8-011125.pdf

     This document is only a draft and is subject to change.  (So beware.)

     Details regarding the older, non-standard 64-bit format were
     determined empirically by examining 64-bit ELF files produced by

   This routine tries to keep line numbers from identical absolute and

   Using the `list' example from the GDB testsuite, which resides in

   files.files[1].name: list0.c
   files.files[1].dir:  /srcdir

   The line number information for list0.c has to end up in a single
   subfile, so that `break /srcdir/list0.c:1' works as expected.
   start_subfile will ensure that this happens provided that we pass the
