Hidden directories (Windows)

[John Emmas <johne53 tiscali co uk>]

1)  In Linux, I can specify a file or directory to be hidden, simply by preceding its name with a period 
('.') but this doesn't work in Windows.  Does glib have any handy function for hiding or unhiding an (already 
existing) Windows directory?

2)  When I'm creating a new directory using g_mkdir_with_parents() I've tended to specify 0775 for the mode 
flags - simply because that's what I've seen in every example.  But presumably there's a range of flags to 
choose from.  Is there a list available anywhere?
