Here's my output.  The only one that differs is the first one.

506 /boot/home/develop/autoconf-2.53b>expr 'a' : '\([^a]\)'
a
507 /boot/home/develop/autoconf-2.53b>expr 'b' : '\([^a]\)'
b
508 /boot/home/develop/autoconf-2.53b>expr '^' : '\([^a]\)'
^
509 /boot/home/develop/autoconf-2.53b>dirname a/b/c
a/b
510 /boot/home/develop/autoconf-2.53b>dirname //1/3///
//1
511 /boot/home/develop/autoconf-2.53b>dirname /1/3///
/1
512 /boot/home/develop/autoconf-2.53b>dirname ./1/3///
/1
513 /boot/home/develop/autoconf-2.53b>dirname ../../2/3///
./../2
514 /boot/home/develop/autoconf-2.53b>dirname //1//3/
