* 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.
