mkdir return status changed from 2.7.2 to 2.9.4

[Jean-Francois Cardoso]

The meaning of the return code of function mkdir has changed from
2.7.2 to 2.9.4 (see the help texts below).

All my brilliant successes (at creating dirs) of the past are now
reported as miserable failures.

Is this an unintended move, to be reversed ?

Otherwise, is there a decent way to write code which would run under
both 2.1.xx and 2.9.xx ?

Cheers, JF

octave:1> help mkdir
mkdir is a built-in function

 -- Built-in Function: [ERR, MSG] = mkdir (DIR)
     Create a directory named DIR.

     If successful, ERR is 0 and MSG is an empty string.  Otherwise,
     ERR is nonzero and MSG contains a system-dependent error message.

GNU Octave, version 2.9.4 (i686-pc-linux-gnu).
octave:1> help mkdir
mkdir is a built-in function

 -- Built-in Function: [STATUS, MSG, MSGID] = mkdir (DIR)
     Create a directory named DIR.

     If successful, STATUS is 1, with MSG and MSGID empty character
     strings.  Otherwise, STATUS is 0, MSG contains a system-dependent
     error message, and MSGID contains a unique message identifier.
