This issue also affects Lazarus 1.6 and FPC 3.0+.

GetWindowsSpecialDir in FPC 3.0.0 and trunk has severe encoding and buffer
overrun issues. SHGetFolderPath links to SHGetFolderPathW if
FPC_UNICODE_RTL is defined. But GetWindowsSpecialDir still calls it as
SHGetFolderPathA, passing under-sized PChar buffer instead of PWideChar.

Working on a fix.
