I was all excited about this and gave it a shot with this morning's cvsup.  First
I got a snd error, disabled sound drivers and just  when I thought that I had it

cc -c -O -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit  -Wnested-externs
-Wstrict-prototypes -Wmissing-prototypes  -Wpointer-arith -Winline -Wuninitializ
ed -Wformat  -fformat-extensions -ansi  -nostdinc -I- -I. -I../.. -I../../../inc
lude  -DKERNEL -include opt_global.h -elf  vers.c
loading kernel
apm.o: In function `apmattach':
apm.o(.text+0x93b): undefined reference to `apm_cs32_limit'
apm.o(.text+0x949): undefined reference to `apm_cs16_limit'
*** Error code 1

Stop.

Suggestions?

Thanks
