I didn't merge the widestring memory handling to fixes and it wasn't
wrong to do so, see the current failures :)
They don't work with checkpointer (see bug report 4125).
Anybody a suggestion how we should handle this? There was a bug report
(http://www.freepascal.org/bugs/showrec.php3?ID=2423) that FPC causes problems
when working with variants and widestrings and passing them to windows.
In delphi, on windows the function NewWideString calls SysAllocStringlen
to allocate the wide string. On Linux, a simple getmem is used.
When freeing the wide string, SysFreeString is used.
I don't see any other way to do it. To make the code 'system
independent' you could introduce a set of procedural variables
GetWideStringMem : Function (Len : Integer) : Pointer;
FreeWideString : procedure(var P : Pointer);
Which are set to defaults on non-win32, and which are set to 2 functions
that call the appropriate windows functions.
