Huh?  Never heard of that rule.  I routinely bootstrap with
CONFIG_SHELL of /bin/ksh or /bin/bash anyway so unless they all share
the bug, I think you may be mistaken.  Consider this:

---file foo---------------------
#!/bin/bash
export VAR=xxx
VAR=yyy
./bar
---file bar---------------------
#!/bin/bash
echo $VAR
--------------------------------

what should running "foo" output?  Under bash-2.03, I get "yyy".
