Fixes for dmd 2.068. - Githubissues

Fixes for dmd 2.068.0.

Because an error occurs when passing a pointer of const string to the CreateWindowEx function on Win64 (Because the function is mistaking an address of const value and a class atom of Windows maybe), I wrote <const string>.dup.ptr.

Fixes for linux isn't required.

I'm not sure I understand why this is necessary.

I wrote this initially (Shell.d):

 void createToolTipHandle () {
     toolTipHandle_ = OS.CreateWindowEx (
         0,
         OS.TOOLTIPS_CLASS.ptr,
         null,

And, When I build and ran the Snippet41. Then I received this error:

$ .\bin\SwtSnippet41.exe
org.eclipse.swt.SWTError.SWTError@java\lang\exceptions.d(22): No more handles

E:\apps\dmdlib\dwt64\org.eclipse.swt.win32.win32.x86\src\org\eclipse\swt\SWT.d(3871)
   :

CreateWindowEx() calling is failed. Error code is 998 (ERROR_NOACCESS).

I don't know the cause of error. But I suspect CreateWindowEx is mistaken a lpWindowName argument and a class atom maybe (See also: CreateWindowEx).

When I create a dynamic variable using .dup, It ran successfully.
