Ouch (and I should have figured that out myself, sorry).
Hence it's a serious bug to test $SHELL at all.

Autoconf 2.59 doesn't have this bug, as it tests the current shell
directly, by running some code in it, rather than by trying to invoke
$SHELL.

Thanks very much for pursuing this.  Will your patch take the Autoconf
2.59 approach for testing the current shell?
