   This would be osenv_intr_save_disable(), which is the only one not
   defined in oskit-mach?

Yep!  Try to cook up your own version of it.

   I don't understand how adding more overwrites can help, because the
   linker already complains about conflicting definitions, but then I don't
   understand the linker very well, so I will try to add a dummy function.

The linker only pulls in an object from an archive if it is needed to
satisfy undefined references.  Since aparently some other code
references osenv_intr_save_disable() and this function can only be
found in the archive, it pulls in the entire module which also defines
the functions in oskit-mach's synch.o, hence the conflicts.  However,
if you provide osenv_intr_save_disable() in oskit-mach's synch.o, the
linker won't pull in oskit's synch.o, and the conflicts disappear.

Your next two problems you will have to solve:

i386-gnu-gcc  -nostdlib -nostartfiles -r -o oskit-kernel.o \
      -Wl,-\( kernel.o clib-routines.o -loskit_clientos -loskit_c
-loskit_kern -loskit_lmm
+-loskit_com -loskit_unsupp -loskit_dev -loskit_linux_dev -loskit_diskpart
-Wl,-\) -lgcc
i386-gnu-ld -Ttext 100000 -o kernel oskit-kernel.o
/usr/i386-gnu/lib/oskit/crtn.o
oskit-kernel.o: In function `alloc_for_oskit':
oskit-kernel.o(.text+0x3a0f4): undefined reference to `ffs'
oskit-kernel.o: In function `picinit':
oskit-kernel.o(.text+0x50ba7): undefined reference to `cli'
make[1]: *** [kernel] Error 1

I kludged around it, and I am too ashamed of my hack to post it
a second time ;)

Good night,
Marcus
