It is not kpsewhich which causes this, it is the call to execute a shell
command and the underlying interpreter which causes these differences.

You could easily wrap the different $ of the shells by wrapping things
in a quotevar  function, so that you could write
  kpsewhich -expand-var quotevar('$SELFAUTOPARENT')

kpsewhich *is* platform independent. The underlying shells are not...
If you write a C program which calls execl(), you'll see that there is
no difference in parsing the $.
