* libgimp/gimpenv.c (gimp_directory): Don't warn about missing
 	home directory on Win32, it is perfectly natural.

	* app/color_notebook.c
	* libgimp/color_selector.h: Bypass the declaration of the exported
 	functions in the header. (Caused different linkage error with MSC,
 	as they are declared dllexport in the source, but naturally not in
 	the header.)
