*grub-0.90-r6 (4 Feb 2002)
*grub-0.91-r1 (4 Feb 2002)

  4 Feb 2002; Daniel Robbins <drobbins@gentoo.org>: grub-0.90-r6.ebuild,
  grub-0.91-r1.ebuild: unset CFLAGS to ensure that GRUB code is i486-compatible,
  a good thing for a boot loader.  Upgraded /boot mounting code to be compatible
  with systems without a dedicated /boot filesystem.  Tweaked GRUB installation
  so that the /boot/grub/*stage* files don't get overwritten, since this could
  mess up the currently-in-the-MBR GRUB.  These fixes also close bug #527.

*grub-0.90-r5 (4 Feb 2002)

  4 Feb 2002; G.Bevin <gbevin@gentoo.org> grub-0.90-r5.ebuild, grub-0.91.ebuild :  
  Added new setup function which detects if /boot is mounted or not, in case
  it's not mounted it will try to do it automatically and in case of a failure
  exit with an error message.
