Fix for miscompiled XDM-AUTHORIZATION-1 key generation and/or validation

[Matthias Klose <doko@cs.tu-berlin.de>]

With current gcc-3.3 CVS on i386 I am unable to reproduce this
one. Please could somebody verify this for powerpc as well?

- get the current gcc-3.3 source package
- in debian/rules.patch, add debian_patches += m68k-update1
- rebuild the package
- rebuild XFree86 with the new compiler.

Thanks, Matthias
