  New Revision: 61950

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61950

  Log:
    there is no guarantee that mode_t is as wide as int
    
    POSIX only defines mode_t to be "an integer typea", and in fact
    MacOS defines it to be uint16_t.  We didn't have NUM2USHORT before
    so it did not make sense but now that we have it.  Why not check
    apptopriately.
