[PATCH: perl@9841] fix a typo for Cwd.xs

[Peter Prymmer]

This one too seemed to slip through the cracks.  The problem 
was first noted by me on VMS with the 9830 kit and the message:

 CC/DECC
 /Include=[]/Standard=Relaxed_ANSI/Prefix=All/Obj=.obj/NoList/NOANSI_ALI

       PerlDir_close(dir);
 ......^
 %CC-W-PTRMISMATCH, In this statement, the referenced type of the
 pointer value "(dir)" is "char", which is not compatible with
 "struct _dirdesc".
 at line number 195 in file DKA500:[PERL.EXT.CWD]CWD.XS;1

Which is more than a little disconcerting (where is a C<char * dir;> 
coming from???)  At any rate here is a fix:

         warn("abs_path: closedir(\"%s\"): %s", dotdots, Strerror(errno));
End of Patch.
