New version of the patch, made after a discussion with Okuji on irc.
The ftoa changes in previous version of this patch might be done later,
if someone confirms they are ok.

2005-07-02  Vincent Pelletier  <subdino2004@yahoo.fr>

    * kern/misc.c
      (grub_strncpy, grub_strncat, grub_strncmp, grub_strncasecmp):
      Changed argument type from int to grub_size_t.
      (grub_printf, grub_vprintf, grub_vsprintf, grub_sprintf): Changed
      return type from int to grub_size_t.
      (grub_strncasecmp): Make return value to also ignore case when we
      reach the end of one string.
    * include/grub/mish.h
      (grub_strncpy, grub_strncat, grub_strncmp,
      grub_strncasecmp, grub_printf, grub_vprintf, grub_sprintf,
      grub_vsprintf): Updated prototypes to match changes in
      kern/misc.c.
