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 destroying what's left of my last clean install.
locore.s depends on a number of files, one of which is assym.s.
assym.s should "#define PAGE_SHIFT ...", but the file is empty (but it
exists!). $PTESHIFT comes from machine/pmap.h, but this file exists
and defines this constant.
here's the make-log, with the offending lines right beneith the error
messages. the formatting comes from the way cpp(1) expands macros:

btw: the .depend in my kernel build staging area lists more files
than locore.s itself includes, and all opt_*.h files are empty, as is
assym.s. i have checked the genassym.sh script and tried the nm(1)
tool, re-installed perl (fearing that this beast was responsible) and
tried to track the problem to the actual point of failure, but the
number of files and procedures involved is too much for me.
this problem needs someone who knows how building the kernel works.
