[Harbour] Changing ULONG to long as string (array?) index / length

[Viktor Szakáts]

Hi Przemek,

What chances to do you see to solve this before release?

Where to start if want to do it? If so, should we use a
special type to make it easy to sync our code to size_t?
(this currently causes lot of casting and also warnings
on msvc64 f.e.)

Brgds,
Viktor
