kernel: locore.s doesn't assemble (fillkpt, $PAGE_SHIFT, $PTESHIFT)
since august 8th, 2003 the kernel on my i386 pentiumIII won't compile.
the problem arises in locore.s with the definition of the constants
$PAGE_SHIFT and $PTESHIFT used in `shr' and `shl' instructions within
the macros `fillkpt' and `fillkptphys'.
i've tried to cvsup(1) RELENG_4 and RELENG_4_8 every day for over a
week now, but kernel builds (as part of a buildworld) don't work
anymore. i have set up an area different from the usual /usr/obj/, so
i can experiment. if somebody has tips for me, i could do a lot
without destroy...
