* fileio.c (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer

signedness issues.

 	(Fexpand_file_name): Likewise.  In particular, newdir might
 	point at constant storage, so make it a const pointer.
 	(Fmake_directory_internal, Fread_file_name): Remove unused vars.

 	* minibuf.c (choose_minibuf_frame_1): Now static.
