        I forgot to check in these changes for a long time. This adds
        incomplete support for VGA console, and this is still very
        buggy. Also, a lot of consideration is required for I18N,
        UNICODE, and VGA font issues. Therefore, assume that this is

        add_mem_region and add them after removing overlaps.
        Also, add only 1/4 of the upper memory to free memory. The rest
        is used for loading OS images. Maybe this is ad hoc, but this

        [PUPA_UTIL] (pupa_fat_fini): Likewise.

        * fs/fat.c [PUPA_UTIL] (pupa_fat_init): Defined. Maybe a better
        way should be implemented.
        [PUPA_UTIL] (pupa_fat_fini): Likewise.

        * disk/i386/pc/biosdisk.c (pupa_biosdisk_call_hook): Increase
        the size of NAME for safety.
        (pupa_biosdisk_iterate): Search hard disks to 0x90 instead of
        0x88.

        * conf/i386-pc.rmk (sbin_UTILITIES): New variable.
        (pupa_setup_SOURCES): Likewise.

        * genmk.rb (Utility#rule): Add $(BUILD_CFLAGS) into the rules.

        * kern/i386/pc/startup.S (push_get_mmap_entry): Revert to a
        bunch of pushl's from pusha, because this destroys the return
        value.

        Use -mrtd and -mregparm=3 to reduce the generated code sizes.
        This means that any missing prototypes could be fatal. Also, you
        must take care when writing assembly code. See the comments at
        the beginning of startup.S, for more details.
        
        * kern/i386/pc/startup.S (pupa_halt): Modified for the new
        compilation mechanism.
        (pupa_chainloader_real_boot): Likewise.
        (pupa_biosdisk_rw_int13_extensions): Likewise.
        (pupa_biosdisk_rw_standard): Likewise.
        (pupa_biosdisk_check_int13_extensions): Likewise.
        (pupa_biosdisk_get_diskinfo_int13_extensions): Likewise.
        (pupa_biosdisk_get_diskinfo_standard): Likewise.
        (pupa_get_memsize): Likewise.
        (pupa_get_mmap_entry): Likewise.
        (pupa_console_putchar): Likewise.
        (pupa_console_setcursor): Likewise.
        (pupa_getrtsecs): Use pushl instead of push.

        * kern/i386/pc/init.c (pupa_machine_init): Use the scratch
        memory instead of the stack for a mmap entry, because some
        BIOSes may ignore the maximum size and overflow.

        * conf/i386-pc.rmk (COMMON_CFLAGS): Added -mrtd and -mregparm=3.

        * genmk.rb (PModule#rule): Compile automatically generated
        sources with module-specific CFLAGS as well as other sources.

2002-12-27  Yoshinori K. Okuji  <okuji@enbug.org>

        * configure.ac: Check ld.
        Replace CFLAGS and CPPFLAGS with BUILD_CFLAGS and BUILD_CPPFLAGS
        respectively, before checking endianness and sizes.

        * Makefile.in (LD): New variable.
        
2002-12-27  Yoshinori K. Okuji  <okuji@enbug.org>

        * Makefile.in (BUILD_CC): CC -> BUILD_CC.
