Minor adjustments: warnings "... not declared or declaration mismatch in class ..."

[Hurricane]

Hi Przemek,

I made two adjustments, let me know if I can send it to you for your review/update in Harbour.

---

HB_CLS_PARAMS_ERR - Show warnings ".. not declared or declaration mismatch in class ..." for any level /W 

• When defined in the .prg file or in the build script, it will activate these warnings (currently, it's only for /W3 builds).
• It maintains compatibility with the current usage mode.

HBMK2 test /W -DHB_CLS_PARAMS_ERR

test.prg(34) Warning W0001  Method <OPEN( cFileName, nMode )> not declared or declaration mismatch in class <TTest>

test.prg(38) Warning W0001  Method <CLOSE()> not declared or declaration mismatch in class <TTest>  

-----------

• We cannot always use W3, whether for application or technical strategy reasons.
• Code editor/IDE assistants (VSCode/xEdit...) help us with parameters (using dynamic or static dictionaries), but when there are differences, it leads to errors, generating RTEs and wasted debugging time.
• Essential for any vendor that creates and distributes libraries (xailer, fivewin, etc.) and, subsequently, users who will use these libraries and editors with code assistant.

---

RESERVED: scope for methods and properties

• The same as EXPORTED: When we have to declare (methods/properties) with public scope, it indicates that their use is restricted/internal, improving code readability.

---

To use the original Harbour files with these features in my builds, I did it differently.

Regards,

Hurricane
