message handling needs to take into account for 64bit windows

** ALSO **

For example, the following code does not compile:

SetWindowLong(hWnd, GWL_WNDPROC, (LONG)MyWndProc);

It should be changed as follows:

SetWindowLongPtr(hWnd, GWLP_WNDPROC, (LONG_PTR)MyWndProc);

//## Win32 API Calls ( Part I )
//##
//## The following Win32 api procs are included below for reference purposes only.  They can be used directly,
//## and statically linked in code, as they run on Windows 95/98.  But their definitions are primarily for automatic
//## code generation and conversion into dynamic loading versions of the same name, as well as providing the codebase
//## with realtime diagnostic and usage information.
//##
//## The proc prefixes "win____" and "net____" designate them as Win95/98 compatible
//##
//## Code automation performed by "win__make_gosswin2_pas()".  A special "default" variable list can be
//## specified, per proc, in the format "[[..a list of semi-colon separated name-value pairs..]]".  This provides the code
//## scanner with additional information, like a return value when the proc is unable to load, along with optional additional
//## information.
//##
//## [win32-api-scanner-start-point] - 30aug2025
//##
{$ifdef emergencyfallback}// - use when dynamic procs need maintanence or due to a failure (Win10+ only)

//## or statically linked in code.  Their definitions are provided primarily for automatic code generation into dynamic
//## loading versions of the same name.  This allows the codebase to function across all flavours of Microsoft Windows
//## without breaking, or preventing the app from starting.  In addition, each dynamic proc provides the codebase with
//## realtime diagnostic and usage information.
//##
//## The proc prefixes "win2____" and "net2____" designate a usage scope beyond Win95/98
