448 NOTE: the pxdbed flag is meaningful also in the not
449 already pxdb processed version of the header,
450 because in case on non-already processed by pxdb files
451 that same bit in the header would be always zero.
452 Why? Because the bit is the leftmost bit of a word
453 which contains a 'length' which is always a positive value
454 so that bit is never set to 1 (otherwise it would be negative)
456 Given the above, we have two choices : either we ignore the
457 size of the header itself and just look at the pxdbed field,
458 or we check the size and then we (for safety and paranoia related
459 issues) check the bit.
460 The first solution is used by DDE, the second by PXDB itself.
461 I am using the second one here, because I already wrote it,
462 and it is the end of a long day.
463 Also, using the first approach would still involve size issues

4661 * Routine description:
4662 * There are a variety of places when scanning the DNTT when we
4663 * need to interpret a "type" field. The simplest and most basic
4664 * example is when we're processing the symbol table record
4665 * for a data symbol (a SVAR or DVAR record). That has
4666 * a "type" field specifying the type of the data symbol. That
4667 * "type" field is either an "immediate" type specification (for the
4668 * fundamental types) or a DNTT pointer (for more complicated types).
4669 * For the more complicated types, we may or may not have already
4670 * processed the pointed-to type. (Multiple data symbols can of course
4671 * share the same type).
4672 * The job of hpread_type_lookup() is to process this "type" field.
4673 * Most of the real work is done in subroutines. Here we interpret
4674 * the immediate flag. If not immediate, chase the DNTT pointer to
4675 * find our way to the SOM record describing the type, switch on
4676 * the SOM kind, and then call an appropriate subroutine depending
4677 * on what kind of type we are constructing. (e.g., an array type,
4678 * a struct/class type, etc).
