as.factor / as.ordered is not written as a generic. This differs from
as.numeric, as.matrix, and other as.*. The following seems to address
this and does not break make check-all.
FWIW, the patch is against r55563, because with r55564 I see
/home/mtmorgan/src/R-devel/src/main/dounzip.c:75:15: error: storage size
of ‘dt’ isn’t known
