         - pxdbed flag is set to 1

         2. not pxdbed and doc
         - DEBUG and HEADER  sections are there
         - header is DOC_info_header type
         - pxdbed flag is set to 0

         3. not pxdbed and not doc
         - DEBUG and HEADER sections are there
         - header is XDB_header type
         - pxdbed flag is set to 0

         NOTE: the pxdbed flag is meaningful also in the not
         already pxdb processed version of the header,
         because in case on non-already processed by pxdb files
         that same bit in the header would be always zero.
         Why? Because the bit is the leftmost bit of a word
         which contains a 'length' which is always a positive value
         so that bit is never set to 1 (otherwise it would be negative)

         Given the above, we have two choices : either we ignore the
         size of the header itself and just look at the pxdbed field,
         or we check the size and then we (for safety and paranoia related
         issues) check the bit.
         The first solution is used by DDE, the second by PXDB itself.
         I am using the second one here, because I already wrote it,
         and it is the end of a long day.
         Also, using the first approach would still involve size issues
         because we need to read in the contents of the header section, and
         give the correct amount of stuff we want to read to the
         get_bfd_section_contents function.  */

 *              are about to "look up"., or else [for fundamental types
 *              like int, float, ...] an "immediate" structure describing
 *              the type.
 *     objfile: ?
 *   Return value: A pointer to a "struct type" (representation of a
 *                 type in GDB's internal symbol table - see gdbtypes.h)
 *   Routine description:
 *     There are a variety of places when scanning the DNTT when we
 *     need to interpret a "type" field. The simplest and most basic 
 *     example is when we're processing the symbol table record
 *     for a data symbol (a SVAR or DVAR record). That has
 *     a "type" field specifying the type of the data symbol. That
 *     "type" field is either an "immediate" type specification (for the
 *     fundamental types) or a DNTT pointer (for more complicated types). 
 *     For the more complicated types, we may or may not have already
 *     processed the pointed-to type. (Multiple data symbols can of course
 *     share the same type).
 *     The job of hpread_type_lookup() is to process this "type" field.
 *     Most of the real work is done in subroutines. Here we interpret
 *     the immediate flag. If not immediate, chase the DNTT pointer to
 *     find our way to the SOM record describing the type, switch on
 *     the SOM kind, and then call an appropriate subroutine depending
 *     on what kind of type we are constructing. (e.g., an array type,
 *     a struct/class type, etc).

/* Because of quirks in HP compilers' treatment of anonymous unions inside
   classes, we have to chase through a chain of threaded FIELD entries.
   If we encounter an anonymous union in the chain, we must recursively skip over
   that too.

   This function does a "next" in the chain of FIELD entries, but transparently
   skips over anonymous unions' fields (recursively).

   Inputs are the number of times to do "next" at the top level, the dnttpointer
   (FIELD) and entry pointer (FIELDP) for the dntt record corresponding to it,
   and the ubiquitous objfile parameter. (Note: FIELDP is a **.)  Return value
   is a dnttpointer for the new field after all the skipped ones */
