I missed that the redundant assignment was added intentionally (I
assumed it was an accident).  It was done in commit f9c316c to
eliminate an uninitialized warning from older GCC.

H.J., do you have a suggestion on an approach for both old GCC and
recent Clang? Perhaps an explicit #if condition on __GNUC__ and
__GNUC_MINOR__ for the redundant assignment?
