Apple kind of rolled their own with the exported function namespace patch
(bash32-054) and didn't end up using the same prefix and suffix as I did
(they used BASH_FUNC< and >, respectively).  Since the Apple bash doesn't
recognize the prefix and suffix I used in the official patches as denoting
an exported function definition, it attempts to create a shell variable
with that name.  It's not a valid identifier, so the attempted variable
assignment fails.  I didn't make the change to ignore invalid identifiers
in the environment until after bash-3.2, so Apple doesn't have that change
and throws an error.
