jeroen 8c8cc20511 2004-03-14 Jeroen Dekkers <jeroen@dekkers.cx>
* Makefile.in: Update copyright.
	* genmodsrc.sh: Likewise.
	* gensymlist.sh: Likewise.
	* term/i386/pc/vga.c: Indent correctly.

	* util/i386/pc/pupa-mkimage.c (usage): Use PACKAGE_BUGREPORT as
	bugreporting address.
	* util/i386/pc/pupa-setup.c (usage): Likewise,
	(main): Call pupa_ext2_init and pupa_ext2_fini.

	* fs/fat.c (log2): Renamed to ...
	(fat_log2): ... this.
	All callers changed.
	* kern/misc.c (memcpy): Alias to pupa_memmove.
	* loader/i386/pc/multiboot.c (pupa_rescue_cmd_multiboot): Fix
	lvalue cast.
	* util/console.c (pupa_ncurses_fini): Return 0.

	* util/i386/pc/biosdisk.c (pupa_util_biosdisk_open)[__linux__]:
	Move fail label here.
	[__GNU__]: Don't warn when using stat.
	(open_device)[!__linux__]: Check if FD < 0 instead of !FD.
	(pupa_util_biosdisk_get_pupa_dev)[__GNU__]: Change type of N to
	long int. Use strtol instead of strtoul.
