Re: [Lazarus] With new Win32 manifest LongPathAware I cannot make long filename

[Denis Kozlov via lazarus]

The new "Long path awareness" option is working!
Apparently, you need to do both, embed the manifest and enable long 
paths in the registry or group policy. Only then you will be able to use 
long paths without the "\\?\" prefix.

To enable via the Local Group Policy Editor, navigate to Local Computer 
Policy > Computer Configuration > Administrative Templates > System > 
Filesystem> Enable Win32 long paths = Enabled.

Tested on Windows 10, Lazarus 2.1.0 r59644, using RenameFile RTL routine.
