2918 /* This is complicated. The child processes return a true native VMS
2919 status which must be saved. But there is an assumption in Perl that
2920 the UNIX child status has some relationship to errno values, so
2921 Perl tries to translate it to text in some of the tests.
2922 In order to get the string translation correct, for the error, errno
2923 must be EVMSERR, but that generates a different text message
2924 than what the test programs are expecting. So an errno value must
2925 be derived from the native status value when an error occurs.
2926 That will hide the true native status message. With this version of
2927 perl, the true native child status can always be retrieved so that
2928 is not a problem. But in this case, Pl_statusvalue and errno may
2929 have different values in them.
