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