Hi Roland,
Since you are in gnu-mach oskit mode, here is another problem.
I am trying to build oskit-mach against the latest oskit: 20000901.
Up until now, I have been using the 20000202 snapshot. Everything builds
fine until it gets to creating kernel.o. Here it complains about multiple
declarations of osenv_intr_{disable,enable,enabled}:
gcc -O -g -DDEBUG -nostdlib -nostartfiles -r -o kernel.o\
-L/usr/local/oskit-20000901/lib -Wl,-\(

-loskit_lmm -loskit_com -loskit_unsupp -loskit_dev -loskit_linux_dev -loskit_diskpart
-Wl,-\) -lgcc

It appears that this somehow involves the gnumach/oskit/osenv_synch.c file.
Removing this file allows the whole thing to compile without anymore errors
or warnings. As great as that sounds, it crashes on boot.
Examining the differences between the two kits yielded the following results:
neal@school:/usr/local/oskit-20000901/lib (1)$ for i in liboskit_kern.a \
liboskit_lmm.a liboskit_com.a liboskit_unsupp.a liboskit_dev.a \

We are still only pulling in the osenv_intr_* once. I just cannot figure this
out. It screams linker madness, however, I have no clue at this point.
Thanks,
