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