I can say it pretty much doesn't work at all on SCO. There is
apparently quite a difference between Solaris and SCO SVR4; the first
thing I had to do was change the lseek() syscall to use 32-bit offsets
instead of 64-bit, for example. SCO binaries also require most of the
iBCS2 emulation to exist as well, so I ended up making svr4.ko depend
on ibcs2.ko. I'm currently stuck trying to get getdents() and fstat()
work.
