On further looking, this looks clearly like an incompatibility
problem between the kernel source and gcc cvs HEAD.

gcc is unhappy with this construction:

#ifdef __BIG_KERNEL__                   # look in setup.S for bootsect_kludge
        bootsect_kludge = 0x220         # 0x200 + 0x20 which is the size of the
        lcall   bootsect_kludge         # bootsector + bootsect_kludge offset

Sorry for the noise.  I'll report the problem to LKML.
