Details:

prefdir is defined rather simply: it returns the value of HOME environment
variable.


function folder = prefdir ()
  folder = getenv ("HOME");
endfunction


This is  just fine on Unix-based systems. However, on my rather vanilla
installation of Windows 8.1, the HOME variable is not defined, so this
function returns the empty string.

The closest I can come to for HOME is HOMEPATH. LOCALAPPDATA may be a better
environment variable to use for prefdir anyway, although in that case you
would want to make sure that the directory is created when requested.
