JM		 2641/* This is complicated. The child processes return a true native VMS
2642 status which must be saved. But there is an assumption in Perl that
2643 the UNIX child status has some relationship to errno values, so
2644 Perl tries to translate it to text in some of the tests.
2645 In order to get the string translation correct, for the error, errno
2646 must be EVMSERR, but that generates a different text message
2647 than what the test programs are expecting. So an errno value must
2648 be derived from the native status value when an error occurs.
2649 That will hide the true native status message. With this version of
2650 perl, the true native child status can always be retrieved so that
2651 is not a problem. But in this case, Pl_statusvalue and errno may
2652 have different values in them.
