re PR fortran/30514 ([4.1 only] zero-sized array wrongly rejected: integer :: i(1:-1))
2007-02-03 Paul Thomas <pault@gcc.gnu.org>
PR fortran/30514
* array.c (match_array_element_spec): If the length of an array is
negative, adjust the upper limit to make it zero length.
PR fortran/30660
* resolve.c (pure_function, resolve_function): Initialize name to
null to clear up build warnings.
(resolve_fl_variable): Look at components explicitly to check for
default initializer, rather than using gfc_default_initializer.
