425 - pxdbed flag is set to 0
427 NOTE: the pxdbed flag is meaningful also in the not
428 already pxdb processed version of the header,
429 because in case on non-already processed by pxdb files
430 that same bit in the header would be always zero.
431 Why? Because the bit is the leftmost bit of a word
432 which contains a 'length' which is always a positive value
433 so that bit is never set to 1 (otherwise it would be negative)
435 Given the above, we have two choices : either we ignore the
436 size of the header itself and just look at the pxdbed field,
437 or we check the size and then we (for safety and paranoia related
438 issues) check the bit.
439 The first solution is used by DDE, the second by PXDB itself.
440 I am using the second one here, because I already wrote it,
441 and it is the end of a long day.
442 Also, using the first approach would still involve size issues
