; If possible please try to verify me, at least your own are of interest
or expertise. Look for HB_BOOL/HB_TRUE/HB_FALSE usage in WINAPI calls,
if you see such thing, it's wrong. Also some, HB_BOOL WINAPI BOOL
implicit conversions may need to be cleaned.
; I didn't touch PP, RDD, SDD and compiler parts yet.
; In few places it's possible that some in-line comments are disaligned
after this operation.

|
*
|
|
* a:b( COUNT() ):c += 1
|
|
*
|

* will be handled as:
|
|

|
*
|
|
* temp := a:b( COUNT() ), temp:c += 1
|
|
*
|
|
* in non-strict mode (-kh).
|
|
* In practice in Clipper it will call COUNT() function two times: the
|
|
* first time before addition and the second one after addition - in Harbour,
|
|
* COUNT() function will be called only once, before addition.
|
|
* The Harbour (non-strict) method is:
