Hi,
Changes in v3:
- Rebase
At the bottom is the range-diff. The only conflicts appeared in the
documentation, so I haven't re-tested.
As said in the v1 discussion, IMO, the interaction of this feature with
forward declarations of array parameters is fine, and the only problem
is in the forward declarations, not in _Countof(). The behavior is
consistent with related features in GCC.
Have a lovely night!
