* library/choosedir.tcl (::tk::dialog::file::chooseDir::Config):

	* library/tkfbox.tcl (::tk::dialog::file::Config): removed the
	extraneous glob on -initialdir after file isdir already returned 1
	and moved cd trick into this case as the else already uses [pwd].
	[Bug: 5181]

	* win/winMain.c: moved extern call out of WinMain func
